1270 \`configure' configures GNU C Runtime Library 1.0 to adapt to many kinds of systems.
1272 Usage: $0 [OPTION]... [VAR=VALUE]...
1274 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1275 VAR=VALUE. See below for descriptions of some of the useful variables.
1277 Defaults for the options are specified in brackets.
1280 -h, --help display this help and exit
1281 --help=short display options specific to this package
1282 --help=recursive display the short help of all the included packages
1283 -V, --version display version information and exit
1284 -q, --quiet, --silent do not print \`checking ...' messages
1285 --cache-file=FILE cache test results in FILE [disabled]
1286 -C, --config-cache alias for \`--cache-file=config.cache'
1287 -n, --no-create do not create output files
1288 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1290 Installation directories:
1291 --prefix=PREFIX install architecture-independent files in PREFIX
1292 [$ac_default_prefix]
1293 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1296 By default, \`make install' will install all the files in
1297 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1298 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1299 for instance \`--prefix=\$HOME'.
1301 For better control, use the options below.
1303 Fine tuning of the installation directories:
1304 --bindir=DIR user executables [EPREFIX/bin]
1305 --sbindir=DIR system admin executables [EPREFIX/sbin]
1306 --libexecdir=DIR program executables [EPREFIX/libexec]

1385 LIBS libraries to pass to the linker

/C
++ preprocessor flags
, e.g.
