1225 \`configure' configures Cygwin toplevel 0 to adapt to many kinds of systems.
1226
1227 Usage: $0 [OPTION]... [VAR=VALUE]...
1228
1229 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1230 VAR=VALUE.  See below for descriptions of some of the useful variables.
1231
1232 Defaults for the options are specified in brackets.
1233
1234 Configuration:
1235   -h, --help              display this help and exit
1236       --help=short        display options specific to this package
1237       --help=recursive    display the short help of all the included packages
1238   -V, --version           display version information and exit
1239   -q, --quiet, --silent   do not print \`checking ...' messages
1240       --cache-file=FILE   cache test results in FILE [disabled]
1241   -C, --config-cache      alias for \`--cache-file=config.cache'
1242   -n, --no-create         do not create output files
1243       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1244
1245 Installation directories:
1246   --prefix=PREFIX         install architecture-independent files in PREFIX
1247                           [$ac_default_prefix]
1248   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1249                           [PREFIX]
1250
1251 By default, \`make install' will install all the files in
1252 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1253 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1254 for instance \`--prefix=\$HOME'.
1255
1256 For better control, use the options below.
1257
1258 Fine tuning of the installation directories:
1259   --bindir=DIR            user executables [EPREFIX/bin]
1260   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1298   --with-cross-bootstrap  do not build programs using the mingw toolchain or

1302                           specify where the windows includes are located
1303   --with-windows-libs=DIR specify where the windows libraries are located
1304
1305 Some influential environment variables:
1306   CC          C compiler command
1307   CFLAGS      C compiler flags
1308   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1309               nonstandard directory <lib dir>
1310   LIBS        libraries to pass to the linker, e.g. -l<library>
1311   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1312               you have headers in a nonstandard directory <include dir>
1313   CXX         C++ compiler command
1314   CXXFLAGS    C++ compiler flags
1315   CPP         C preprocessor
1316
1317 Use these variables to override the choices made by `configure' or to help
1318 it to find libraries and programs with nonstandard names/locations.
