1230 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1231
1232 Usage: $0 [OPTION]... [VAR=VALUE]...
1233
1234 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1235 VAR=VALUE.  See below for descriptions of some of the useful variables.
1236
1237 Defaults for the options are specified in brackets.
1238
1239 Configuration:
1240   -h, --help              display this help and exit
1241       --help=short        display options specific to this package
1242       --help=recursive    display the short help of all the included packages
1243   -V, --version           display version information and exit
1244   -q, --quiet, --silent   do not print \`checking...' messages
1245       --cache-file=FILE   cache test results in FILE [disabled]
1246   -C, --config-cache      alias for \`--cache-file=config.cache'
1247   -n, --no-create         do not create output files
1248       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1249
1250 Installation directories:
1251   --prefix=PREFIX         install architecture-independent files in PREFIX
1252                           [$ac_default_prefix]
1253   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1254                           [PREFIX]
1255
1256 By default, \`make install' will install all the files in
1257 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1258 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1259 for instance \`--prefix=\$HOME'.
1260
1261 For better control, use the options below.

1328   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1329   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1330   --with-system-libunwind use installed libunwind
1331   --with-glibc-version=M.N
1332                           assume GCC used with glibc version M.N or later
1333
1334 Some influential environment variables:
1335   CC          C compiler command
1336   CFLAGS      C compiler flags
1337   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1338               nonstandard directory <lib dir>
1339   LIBS        libraries to pass to the linker, e.g. -l<library>
1340   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1341               you have headers in a nonstandard directory <include dir>
1342   CPP         C preprocessor
1343
1344 Use these variables to override the choices made by `configure' or to help
1345 it to find libraries and programs with nonstandard names/locations.
