1238 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1239
1240 Usage: $0 [OPTION]... [VAR=VALUE]...
1241
1242 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1243 VAR=VALUE.  See below for descriptions of some of the useful variables.
1244
1245 Defaults for the options are specified in brackets.
1246
1247 Configuration:
1248   -h, --help              display this help and exit
1249       --help=short        display options specific to this package
1250       --help=recursive    display the short help of all the included packages
1251   -V, --version           display version information and exit
1252   -q, --quiet, --silent   do not print \`checking...' messages
1253       --cache-file=FILE   cache test results in FILE [disabled]
1254   -C, --config-cache      alias for \`--cache-file=config.cache'
1255   -n, --no-create         do not create output files
1256       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1257
1258 Installation directories:
1259   --prefix=PREFIX         install architecture-independent files in PREFIX
1260                           [$ac_default_prefix]
1261   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1262                           [PREFIX]
1263
1264 By default, \`make install' will install all the files in
1265 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1266 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1267 for instance \`--prefix=\$HOME'.
1268
1269 For better control, use the options below.

1347 Some influential environment variables:
1348   CC          C compiler command
1349   CFLAGS      C compiler flags
1350   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1351               nonstandard directory <lib dir>
1352   LIBS        libraries to pass to the linker, e.g. -l<library>
1353   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1354               you have headers in a nonstandard directory <include dir>
1355   CPP         C preprocessor
1356
1357 Use these variables to override the choices made by `configure' or to help
1358 it to find libraries and programs with nonstandard names/locations.
