1221 \`configure' configures Cygwin toplevel 0 to adapt to many kinds of systems.
1222
1223 Usage: $0 [OPTION]... [VAR=VALUE]...
1224
1225 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1226 VAR=VALUE.  See below for descriptions of some of the useful variables.
1227
1228 Defaults for the options are specified in brackets.
1229
1230 Configuration:
1231   -h, --help              display this help and exit
1232       --help=short        display options specific to this package
1233       --help=recursive    display the short help of all the included packages
1234   -V, --version           display version information and exit
1235   -q, --quiet, --silent   do not print \`checking ...' messages
1236       --cache-file=FILE   cache test results in FILE [disabled]
1237   -C, --config-cache      alias for \`--cache-file=config.cache'
1238   -n, --no-create         do not create output files
1239       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1240
1241 Installation directories:
1242   --prefix=PREFIX         install architecture-independent files in PREFIX
1243                           [$ac_default_prefix]
1244   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1245                           [PREFIX]
1246
1247 By default, \`make install' will install all the files in
1248 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1249 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1250 for instance \`--prefix=\$HOME'.
1251
1252 For better control, use the options below.

1254 Fine tuning of the installation directories:
1255   --bindir=DIR            user executables [EPREFIX/bin]

1301 Some influential environment variables:
1302   CC          C compiler command
1303   CFLAGS      C compiler flags
1304   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1305               nonstandard directory <lib dir>
1306   LIBS        libraries to pass to the linker, e.g. -l<library>
1307   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1308               you have headers in a nonstandard directory <include dir>
1309   CXX         C++ compiler command
1310   CXXFLAGS    C++ compiler flags
1311   CPP         C preprocessor
1312
1313 Use these variables to override the choices made by `configure' or to help
1314 it to find libraries and programs with nonstandard names/locations.
