1271 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1272
1273 Usage: $0 [OPTION]... [VAR=VALUE]...
1274
1275 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1276 VAR=VALUE.  See below for descriptions of some of the useful variables.
1277
1278 Defaults for the options are specified in brackets.
1279
1280 Configuration:
1281   -h, --help              display this help and exit
1282       --help=short        display options specific to this package
1283       --help=recursive    display the short help of all the included packages
1284   -V, --version           display version information and exit
1285   -q, --quiet, --silent   do not print \`checking ...' messages
1286       --cache-file=FILE   cache test results in FILE [disabled]
1287   -C, --config-cache      alias for \`--cache-file=config.cache'
1288   -n, --no-create         do not create output files
1289       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1290
1291 Installation directories:
1292   --prefix=PREFIX         install architecture-independent files in PREFIX
1293                           [$ac_default_prefix]
1294   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1295                           [PREFIX]
1296
1297 By default, \`make install' will install all the files in
1298 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1299 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1300 for instance \`--prefix=\$HOME'.
1301
1302 For better control, use the options below.

1351   --disable-largefile     omit support for large files
1352   --enable-decimal-float={no,yes,bid,dpd}
1353                         enable decimal float extension to C.  Selecting 'bid'

1361   --disable-tm-clone-registry    disable TM clone registry
1362   --enable-tls            Use thread-local storage [default=yes]
1363
1364 Optional Packages:
1365   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1366   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1367   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1368   --with-cross-host=HOST           Configuring with a cross compiler
1369   --with-ld               arrange to use the specified ld (full pathname)
1370   --with-aix-soname=aix|svr4|both
1371                           shared library versioning (aka "SONAME") variant to
1372                           provide on AIX
1373   --with-toolexeclibdir=DIR
1374                           install libraries built with a cross compiler within
1375                           DIR
1376   --with-slibdir=DIR      shared libraries in DIR LIBDIR
1377   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1378   --with-system-libunwind use installed libunwind
1379   --with-glibc-version=M.N
1380                           assume GCC used with glibc version M.N or later
1381   --with-gcc-major-version-only
1382                           use only GCC major number in filesystem paths
1383
1384 Some influential environment variables:
1385   CC          C compiler command
1386   CFLAGS      C compiler flags
1387   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1388               nonstandard directory <lib dir>
1389   LIBS        libraries to pass to the linker, e.g. -l<library>
1390   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1391               you have headers in a nonstandard directory <include dir>
1392   CPP         C preprocessor
1393
1394 Use these variables to override the choices made by `configure' or to help
1395 it to find libraries and programs with nonstandard names/locations.
