1222 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1223
1224 Usage: $0 [OPTION]... [VAR=VALUE]...
1225
1226 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1227 VAR=VALUE.  See below for descriptions of some of the useful variables.
1228
1229 Defaults for the options are specified in brackets.
1230
1231 Configuration:
1232   -h, --help              display this help and exit
1233       --help=short        display options specific to this package
1234       --help=recursive    display the short help of all the included packages
1235   -V, --version           display version information and exit
1236   -q, --quiet, --silent   do not print \`checking...' messages
1237       --cache-file=FILE   cache test results in FILE [disabled]
1238   -C, --config-cache      alias for \`--cache-file=config.cache'
1239   -n, --no-create         do not create output files
1240       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1241
1242 Installation directories:
1243   --prefix=PREFIX         install architecture-independent files in PREFIX
1244                           [$ac_default_prefix]
1245   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1246                           [PREFIX]
1247
1248 By default, \`make install' will install all the files in
1249 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1250 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1251 for instance \`--prefix=\$HOME'.
1252
1253 For better control, use the options below.

1325 Some influential environment variables:
1326   CC          C compiler command
1327   CFLAGS      C compiler flags
1328   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1329               nonstandard directory <lib dir>
1330   LIBS        libraries to pass to the linker, e.g. -l<library>
1331   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1332               you have headers in a nonstandard directory <include dir>
1333   CPP         C preprocessor
1334
1335 Use these variables to override the choices made by `configure' or to help
1336 it to find libraries and programs with nonstandard names/locations.
