1235 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1236
1237 Usage: $0 [OPTION]... [VAR=VALUE]...
1238
1239 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1240 VAR=VALUE.  See below for descriptions of some of the useful variables.
1241
1242 Defaults for the options are specified in brackets.
1243
1244 Configuration:
1245   -h, --help              display this help and exit
1246       --help=short        display options specific to this package
1247       --help=recursive    display the short help of all the included packages
1248   -V, --version           display version information and exit
1249   -q, --quiet, --silent   do not print \`checking...' messages
1250       --cache-file=FILE   cache test results in FILE [disabled]
1251   -C, --config-cache      alias for \`--cache-file=config.cache'
1252   -n, --no-create         do not create output files
1253       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1254
1255 Installation directories:
1256   --prefix=PREFIX         install architecture-independent files in PREFIX
1257                           [$ac_default_prefix]
1258   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1259                           [PREFIX]
1260
1261 By default, \`make install' will install all the files in
1262 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1263 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1264 for instance \`--prefix=\$HOME'.
1265
1266 For better control, use the options below.

1344 Some influential environment variables:
1345   CC          C compiler command
1346   CFLAGS      C compiler flags
1347   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1348               nonstandard directory <lib dir>
1349   LIBS        libraries to pass to the linker, e.g. -l<library>
1350   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1351               you have headers in a nonstandard directory <include dir>
1352   CPP         C preprocessor
1353
1354 Use these variables to override the choices made by `configure' or to help
1355 it to find libraries and programs with nonstandard names/locations.
