1233 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1234
1235 Usage: $0 [OPTION]... [VAR=VALUE]...
1236
1237 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1238 VAR=VALUE.  See below for descriptions of some of the useful variables.
1239
1240 Defaults for the options are specified in brackets.
1241
1242 Configuration:
1243   -h, --help              display this help and exit
1244       --help=short        display options specific to this package
1245       --help=recursive    display the short help of all the included packages
1246   -V, --version           display version information and exit
1247   -q, --quiet, --silent   do not print \`checking...' messages
1248       --cache-file=FILE   cache test results in FILE [disabled]
1249   -C, --config-cache      alias for \`--cache-file=config.cache'
1250   -n, --no-create         do not create output files
1251       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1252
1253 Installation directories:
1254   --prefix=PREFIX         install architecture-independent files in PREFIX
1255                           [$ac_default_prefix]
1256   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1257                           [PREFIX]
1258
1259 By default, \`make install' will install all the files in
1260 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1261 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1262 for instance \`--prefix=\$HOME'.
1263
1264 For better control, use the options below.

1331                           provide on AIX
1332   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1333   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1334   --with-system-libunwind use installed libunwind
1335   --with-glibc-version=M.N
1336                           assume GCC used with glibc version M.N or later
1337   --with-gcc-major-version-only
1338                           use only GCC major number in filesystem paths
1339
1340 Some influential environment variables:
1341   CC          C compiler command
1342   CFLAGS      C compiler flags
1343   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1344               nonstandard directory <lib dir>
1345   LIBS        libraries to pass to the linker, e.g. -l<library>
1346   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1347               you have headers in a nonstandard directory <include dir>
1348   CPP         C preprocessor
1349
1350 Use these variables to override the choices made by `configure' or to help
1351 it to find libraries and programs with nonstandard names/locations.
