1268 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1269
1270 Usage: $0 [OPTION]... [VAR=VALUE]...
1271
1272 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1273 VAR=VALUE.  See below for descriptions of some of the useful variables.
1274
1275 Defaults for the options are specified in brackets.
1276
1277 Configuration:
1278   -h, --help              display this help and exit
1279       --help=short        display options specific to this package
1280       --help=recursive    display the short help of all the included packages
1281   -V, --version           display version information and exit
1282   -q, --quiet, --silent   do not print \`checking ...' messages
1283       --cache-file=FILE   cache test results in FILE [disabled]
1284   -C, --config-cache      alias for \`--cache-file=config.cache'
1285   -n, --no-create         do not create output files
1286       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1287
1288 Installation directories:
1289   --prefix=PREFIX         install architecture-independent files in PREFIX
1290                           [$ac_default_prefix]
1291   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1292                           [PREFIX]
1293
1294 By default, \`make install' will install all the files in
1295 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1296 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1297 for instance \`--prefix=\$HOME'.
1298
1299 For better control, use the options below.

1348   --disable-largefile     omit support for large files

1350                         enable decimal float extension to C.  Selecting 'bid'

1360 Optional Packages:
1361   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1362   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1363   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1364   --with-cross-host=HOST           Configuring with a cross compiler
1365   --with-ld               arrange to use the specified ld (full pathname)
1366   --with-aix-soname=aix|svr4|both
1367                           shared library versioning (aka "SONAME") variant to
1368                           provide on AIX
1369   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1370   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1371   --with-system-libunwind use installed libunwind
1372   --with-glibc-version=M.N
1373                           assume GCC used with glibc version M.N or later
1374   --with-gcc-major-version-only
1375                           use only GCC major number in filesystem paths
1376
1377 Some influential environment variables:
1378   CC          C compiler command
1379   CFLAGS      C compiler flags
1380   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1381               nonstandard directory <lib dir>
1382   LIBS        libraries to pass to the linker, e.g. -l<library>
1383   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1384               you have headers in a nonstandard directory <include dir>
1385   CPP         C preprocessor
1386
1387 Use these variables to override the choices made by `configure' or to help
1388 it to find libraries and programs with nonstandard names/locations.
