318 --disable-static do not build static libraries
319 --disable-fast-install do not optimize for fast installation
320 --enable-dlopen enable dlopen support
321 --enable-win32-dll enable building dlls on win32 hosts
322 --help display this help and exit
323 --no-verify do not verify that HOST is a valid host type
324 -o, --output=FILE specify the output file [default=$default_ofile]
325 --quiet same as \`--silent'
326 --silent do not print informational messages
327 --srcdir=DIR find \`config.guess' in DIR
328 --version output version information and exit
329 --add-tag=TAG append an alternate configuration
330 --with-gcc assume that the GNU C compiler will be used
