-/* Character set handling for C-family languages.
-
- Terminological note: In what follows, "charset" or "character set"
- will be taken to mean both an abstract set of characters and an
- encoding for that set.
-
- The C99 standard discusses two character sets: source and execution.
- The source character set is used for internal processing in translation
- phases 1 through 4; the execution character set is used thereafter.
- Both are required by 5.2.1.2p1 to be multibyte encodings, not wide
- character encodings (see 3.7.2, 3.7.3 for the standardese meanings
- of these terms). Furthermore, the "basic character set" (listed in
- 5.2.1p3) is to be encoded in each with values one byte wide, and is
- to appear in the initial shift state.
-
- It is not explicitly mentioned, but there is also a "wide execution
- character set" used to encode wide character constants and wide
- string literals; this is supposed to be the result of applying the
- standard library function mbstowcs() to an equivalent narrow string
- (6.4.5p5). However, the behavior of hexadecimal and octal
- \-escapes is at odds with this; they are supposed to be translated
- directly to wchar_t values (6.4.4.4p5,6).
-
- The source character set is not necessarily the character set used
- to encode physical source files on disk; translation phase 1 converts
- from whatever that encoding is to the source character set.
-
- The presence of universal character names in C99 (6.4.3 et seq.)
- forces the source character set to be isomorphic to ISO 10646,
- that is, Unicode. There is no such constraint on the execution
- character set; note also that the conversion from source to
- execution character set does not occur for identifiers (5.1.1.2p1#5).
-
- For convenience of implementation, the source character set's
- encoding of the basic character set should be identical to the
- execution character set OF THE HOST SYSTEM's encoding of the basic
- character set, and it should not be a state-dependent encoding.
-
- cpplib uses UTF-8 or UTF-EBCDIC for the source character set,
- depending on whether the host is based on ASCII or EBCDIC (see
- respectively Unicode section 2.3/ISO10646 Amendment 2, and Unicode
- Technical Report #16). With limited exceptions, it relies on the
- system library's iconv() primitive to do charset conversion
- (specified in SUSv2). */

-
-/* Conversions between UTF-8 and UTF-16/32 are implemented by custom
- logic. This is because a depressing number of systems lack iconv,
- or have have iconv libraries that do not do these conversions, so
- we need a fallback implementation for them. To ensure the fallback
- doesn't break due to neglect, it is used on all systems.
-
- UTF-32 encoding is nice and simple: a four-byte binary number,
- constrained to the range 00000000-7FFFFFFF to avoid questions of
- signedness. We do have to cope with big- and little-endian
- variants.
-
- UTF-16 encoding uses two-byte binary numbers, again in big- and
- little-endian variants, for all values in the 00000000-0000FFFF
- range. Values in the 00010000-0010FFFF range are encoded as pairs
- of two-byte numbers, called "surrogate pairs": given a number S in
- this range, it is mapped to a pair (H, L) as follows:
-
- H = (S - 0x10000) / 0x400 + 0xD800
- L = (S - 0x10000) % 0x400 + 0xDC00
-
- Two-byte values in the D800...DFFF range are ill-formed except as a
- component of a surrogate pair. Even if the encoding within a
- two-byte value is little-endian, the H member of the surrogate pair
- comes first.
-
- There is no way to encode values in the 00110000-7FFFFFFF range,
- which is not currently a problem as there are no assigned code
- points in that range; however, the author expects that it will
- eventually become necessary to abandon UTF-16 due to this
- limitation. Note also that, because of these pairs, UTF-16 does
- not meet the requirements of the C standard for a wide character
- encoding (see 3.7.3 and 6.4.4.4p11).
-
- UTF-8 encoding looks like this:
-
- value range encoded as
- 00000000-0000007F 0xxxxxxx
- 00000080-000007FF 110xxxxx 10xxxxxx
- 00000800-0000FFFF 1110xxxx 10xxxxxx 10xxxxxx
- 00010000-001FFFFF 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx
- 00200000-03FFFFFF 111110xx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx
- 04000000-7FFFFFFF 1111110x 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx
-
- Values in the 0000D800 ... 0000DFFF range (surrogates) are invalid,
- which means that three-byte sequences ED xx yy, with A0 <= xx <= BF,
- never occur. Note also that any value that can be encoded by a
- given row of the table can also be encoded by all successive rows,
- but this is not done; only the shortest possible encoding for any
- given value is valid. For instance, the character 07C0 could be
- encoded as any of DF 80, E0 9F 80, F0 80 9F 80, F8 80 80 9F 80, or
- FC 80 80 80 9F 80. Only the first is valid.
-
- An implementation note: the transformation from UTF-16 to UTF-8, or
- vice versa, is easiest done by using UTF-32 as an intermediary. */
-

- UTF-32 in a cppchar_t, or vice versa; this avoids an extra marshal/unmarshal

- FILE is a structure containing details about the file that was

-
- START_DIR is the starting location of the search in the include

- they don't cause cache hits with normal include-chain lookups.
-
- If START_DIR is NULL then the entry is for a directory, not a file,
- and the directory is in DIR. Since the starting point in a file
- lookup chain is never NULL, this means that simple pointer
- comparisons against START_DIR can be made to determine cache hits
- in file lookups.
-
- If a cache lookup fails because of e.g. an extra "./" in the path,
- then nothing will break. It is just less efficient as CPP will
- have to do more work re-preprocessing the file, and/or comparing
- its contents against earlier once-only files.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+/* Character set handling for C-family languages.
+
+ Terminological note: In what follows, "charset" or "character set"
+ will be taken to mean both an abstract set of characters and an
+ encoding for that set.
+
+ The C99 standard discusses two character sets: source and execution.
+ The source character set is used for internal processing in translation
+ phases 1 through 4; the execution character set is used thereafter.
+ Both are required by 5.2.1.2p1 to be multibyte encodings, not wide
+ character encodings (see 3.7.2, 3.7.3 for the standardese meanings
+ of these terms). Furthermore, the "basic character set" (listed in
+ 5.2.1p3) is to be encoded in each with values one byte wide, and is
+ to appear in the initial shift state.
+
+ It is not explicitly mentioned, but there is also a "wide execution
+ character set" used to encode wide character constants and wide
+ string literals; this is supposed to be the result of applying the
+ standard library function mbstowcs() to an equivalent narrow string
+ (6.4.5p5). However, the behavior of hexadecimal and octal
+ \-escapes is at odds with this; they are supposed to be translated
+ directly to wchar_t values (6.4.4.4p5,6).
+
+ The source character set is not necessarily the character set used
+ to encode physical source files on disk; translation phase 1 converts
+ from whatever that encoding is to the source character set.
+
+ The presence of universal character names in C99 (6.4.3 et seq.)
+ forces the source character set to be isomorphic to ISO 10646,
+ that is, Unicode. There is no such constraint on the execution
+ character set; note also that the conversion from source to
+ execution character set does not occur for identifiers (5.1.1.2p1#5).
+
+ For convenience of implementation, the source character set's
+ encoding of the basic character set should be identical to the
+ execution character set OF THE HOST SYSTEM's encoding of the basic
+ character set, and it should not be a state-dependent encoding.
+
+ cpplib uses UTF-8 or UTF-EBCDIC for the source character set,
+ depending on whether the host is based on ASCII or EBCDIC (see
+ respectively Unicode section 2.3/ISO10646 Amendment 2, and Unicode
+ Technical Report #16). With limited exceptions, it relies on the
+ system library's iconv() primitive to do charset conversion
+ (specified in SUSv2). */

+
+/* Conversions between UTF-8 and UTF-16/32 are implemented by custom
+ logic. This is because a depressing number of systems lack iconv,
+ or have have iconv libraries that do not do these conversions, so
+ we need a fallback implementation for them. To ensure the fallback
+ doesn't break due to neglect, it is used on all systems.
+
+ UTF-32 encoding is nice and simple: a four-byte binary number,
+ constrained to the range 00000000-7FFFFFFF to avoid questions of
+ signedness. We do have to cope with big- and little-endian
+ variants.
+
+ UTF-16 encoding uses two-byte binary numbers, again in big- and
+ little-endian variants, for all values in the 00000000-0000FFFF
+ range. Values in the 00010000-0010FFFF range are encoded as pairs
+ of two-byte numbers, called "surrogate pairs": given a number S in
+ this range, it is mapped to a pair (H, L) as follows:
+
+ H = (S - 0x10000) / 0x400 + 0xD800
+ L = (S - 0x10000) % 0x400 + 0xDC00
+
+ Two-byte values in the D800...DFFF range are ill-formed except as a
+ component of a surrogate pair. Even if the encoding within a
+ two-byte value is little-endian, the H member of the surrogate pair
+ comes first.
+
+ There is no way to encode values in the 00110000-7FFFFFFF range,
+ which is not currently a problem as there are no assigned code
+ points in that range; however, the author expects that it will
+ eventually become necessary to abandon UTF-16 due to this
+ limitation. Note also that, because of these pairs, UTF-16 does
+ not meet the requirements of the C standard for a wide character
+ encoding (see 3.7.3 and 6.4.4.4p11).
+
+ UTF-8 encoding looks like this:
+
+ value range encoded as
+ 00000000-0000007F 0xxxxxxx
+ 00000080-000007FF 110xxxxx 10xxxxxx
+ 00000800-0000FFFF 1110xxxx 10xxxxxx 10xxxxxx
+ 00010000-001FFFFF 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx
+ 00200000-03FFFFFF 111110xx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx
+ 04000000-7FFFFFFF 1111110x 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx
+
+ Values in the 0000D800 ... 0000DFFF range (surrogates) are invalid,
+ which means that three-byte sequences ED xx yy, with A0 <= xx <= BF,
+ never occur. Note also that any value that can be encoded by a
+ given row of the table can also be encoded by all successive rows,
+ but this is not done; only the shortest possible encoding for any
+ given value is valid. For instance, the character 07C0 could be
+ encoded as any of DF 80, E0 9F 80, F0 80 9F 80, F8 80 80 9F 80, or
+ FC 80 80 80 9F 80. Only the first is valid.
+
+ An implementation note: the transformation from UTF-16 to UTF-8, or
+ vice versa, is easiest done by using UTF-32 as an intermediary. */

+ lookup chain is never NULL, this means that simple pointer
+ comparisons against START_DIR can be made to determine cache hits
+ in file lookups.
+
+ If a cache lookup fails because of e.g. an extra "./" in the path,
