1253 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1254
1255 Usage: $0 [OPTION]... [VAR=VALUE]...
1256
1257 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1258 VAR=VALUE.  See below for descriptions of some of the useful variables.
1259
1260 Defaults for the options are specified in brackets.
1261
1262 Configuration:
1263   -h, --help              display this help and exit
1264       --help=short        display options specific to this package
1265       --help=recursive    display the short help of all the included packages
1266   -V, --version           display version information and exit
1267   -q, --quiet, --silent   do not print \`checking...' messages
1268       --cache-file=FILE   cache test results in FILE [disabled]
1269   -C, --config-cache      alias for \`--cache-file=config.cache'
1270   -n, --no-create         do not create output files
1271       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1272
1273 Installation directories:
1274   --prefix=PREFIX         install architecture-independent files in PREFIX
1275                           [$ac_default_prefix]
1276   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1277                           [PREFIX]
1278
1279 By default, \`make install' will install all the files in
1280 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1281 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1282 for instance \`--prefix=\$HOME'.
1283
1284 For better control, use the options below.

1341   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1342   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1343   --with-cross-host=HOST           Configuring with a cross compiler
1344   --with-ld               arrange to use the specified ld (full pathname)
1345   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1346   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1347   --with-system-libunwind use installed libunwind
1348
1349 Some influential environment variables:
1350   CC          C compiler command
1351   CFLAGS      C compiler flags
1352   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1353               nonstandard directory <lib dir>
1354   LIBS        libraries to pass to the linker, e.g. -l<library>
1355   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1356               you have headers in a nonstandard directory <include dir>
1357   CPP         C preprocessor
1358
1359 Use these variables to override the choices made by `configure' or to help
1360 it to find libraries and programs with nonstandard names/locations.
