 798
 799 Defaults for the options are specified in brackets.

 801 Configuration:
 802   -h, --help              display this help and exit
 803       --help=short        display options specific to this package
 804       --help=recursive    display the short help of all the included packages
 805   -V, --version           display version information and exit
 806   -q, --quiet, --silent   do not print \`checking...' messages
 807       --cache-file=FILE   cache test results in FILE [disabled]
 808   -C, --config-cache      alias for \`--cache-file=config.cache'
 809   -n, --no-create         do not create output files

 906   CC          C compiler command
 907   CFLAGS      C compiler flags
 908   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 909               nonstandard directory <lib dir>
 910   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 911               headers in a nonstandard directory <include dir>
 912   CPP         C preprocessor
 913   CXX         C++ compiler command
 914   CXXFLAGS    C++ compiler flags
 915
 916 Use these variables to override the choices made by `configure' or to help
 917 it to find libraries and programs with nonstandard names/locations.
