1223 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1224
1225 Usage: $0 [OPTION]... [VAR=VALUE]...
1226
1227 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1228 VAR=VALUE.  See below for descriptions of some of the useful variables.
1229
1230 Defaults for the options are specified in brackets.
1231
1232 Configuration:
1233   -h, --help              display this help and exit
1234       --help=short        display options specific to this package
1235       --help=recursive    display the short help of all the included packages
1236   -V, --version           display version information and exit
1237   -q, --quiet, --silent   do not print \`checking...' messages
1238       --cache-file=FILE   cache test results in FILE [disabled]
1239   -C, --config-cache      alias for \`--cache-file=config.cache'
1240   -n, --no-create         do not create output files
1241       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1242
1243 Installation directories:
1244   --prefix=PREFIX         install architecture-independent files in PREFIX
1245                           [$ac_default_prefix]
1246   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1247                           [PREFIX]
1248
1249 By default, \`make install' will install all the files in
1250 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1251 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1252 for instance \`--prefix=\$HOME'.
1253
1254 For better control, use the options below.

1326 Some influential environment variables:
1327   CC          C compiler command
1328   CFLAGS      C compiler flags
1329   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1330               nonstandard directory <lib dir>
1331   LIBS        libraries to pass to the linker, e.g. -l<library>
1332   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1333               you have headers in a nonstandard directory <include dir>
1334   CPP         C preprocessor
1335
1336 Use these variables to override the choices made by `configure' or to help
1337 it to find libraries and programs with nonstandard names/locations.
