1270 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1271
1272 Usage: $0 [OPTION]... [VAR=VALUE]...
1273
1274 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1275 VAR=VALUE.  See below for descriptions of some of the useful variables.
1276
1277 Defaults for the options are specified in brackets.
1278
1279 Configuration:
1280   -h, --help              display this help and exit
1281       --help=short        display options specific to this package
1282       --help=recursive    display the short help of all the included packages
1283   -V, --version           display version information and exit
1284   -q, --quiet, --silent   do not print \`checking ...' messages
1285       --cache-file=FILE   cache test results in FILE [disabled]
1286   -C, --config-cache      alias for \`--cache-file=config.cache'
1287   -n, --no-create         do not create output files
1288       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1289
1290 Installation directories:
1291   --prefix=PREFIX         install architecture-independent files in PREFIX
1292                           [$ac_default_prefix]
1293   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1294                           [PREFIX]
1295
1296 By default, \`make install' will install all the files in
1297 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1298 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1299 for instance \`--prefix=\$HOME'.
1300
1301 For better control, use the options below.

1350   --disable-largefile     omit support for large files
1351   --enable-decimal-float={no,yes,bid,dpd}
1352                         enable decimal float extension to C.  Selecting 'bid'

1360   --disable-tm-clone-registry    disable TM clone registry

1363 Optional Packages:
1364   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1365   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1366   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1367   --with-cross-host=HOST           Configuring with a cross compiler
1368   --with-ld               arrange to use the specified ld (full pathname)
1369   --with-aix-soname=aix|svr4|both
1370                           shared library versioning (aka "SONAME") variant to
1371                           provide on AIX
1372   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1373   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1374   --with-system-libunwind use installed libunwind
1375   --with-glibc-version=M.N
1376                           assume GCC used with glibc version M.N or later
1377   --with-gcc-major-version-only
1378                           use only GCC major number in filesystem paths
1379
1380 Some influential environment variables:
1381   CC          C compiler command
1382   CFLAGS      C compiler flags
1383   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1384               nonstandard directory <lib dir>
1385   LIBS        libraries to pass to the linker, e.g. -l<library>
1386   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1387               you have headers in a nonstandard directory <include dir>
1388   CPP         C preprocessor
1389
1390 Use these variables to override the choices made by `configure' or to help
1391 it to find libraries and programs with nonstandard names/locations.
