1232 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1233
1234 Usage: $0 [OPTION]... [VAR=VALUE]...
1235
1236 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1237 VAR=VALUE.  See below for descriptions of some of the useful variables.
1238
1239 Defaults for the options are specified in brackets.
1240
1241 Configuration:
1242   -h, --help              display this help and exit
1243       --help=short        display options specific to this package
1244       --help=recursive    display the short help of all the included packages
1245   -V, --version           display version information and exit
1246   -q, --quiet, --silent   do not print \`checking...' messages
1247       --cache-file=FILE   cache test results in FILE [disabled]
1248   -C, --config-cache      alias for \`--cache-file=config.cache'
1249   -n, --no-create         do not create output files
1250       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1251
1252 Installation directories:
1253   --prefix=PREFIX         install architecture-independent files in PREFIX
1254                           [$ac_default_prefix]
1255   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1256                           [PREFIX]
1257
1258 By default, \`make install' will install all the files in
1259 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1260 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1261 for instance \`--prefix=\$HOME'.
1262
1263 For better control, use the options below.

1328                           shared library versioning (aka "SONAME") variant to
1329                           provide on AIX
1330   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1331   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1332   --with-system-libunwind use installed libunwind
1333   --with-glibc-version=M.N
1334                           assume GCC used with glibc version M.N or later
1335   --with-gcc-major-version-only
1336                           use only GCC major number in filesystem paths
1337
1338 Some influential environment variables:
1339   CC          C compiler command
1340   CFLAGS      C compiler flags
1341   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1342               nonstandard directory <lib dir>
1343   LIBS        libraries to pass to the linker, e.g. -l<library>
1344   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1345               you have headers in a nonstandard directory <include dir>
1346   CPP         C preprocessor
1347
1348 Use these variables to override the choices made by `configure' or to help
1349 it to find libraries and programs with nonstandard names/locations.
