318 --debug enable verbose shell tracing
319 --disable-shared do not build shared libraries
320 --disable-static do not build static libraries
321 --disable-fast-install do not optimize for fast installation
322 --enable-dlopen enable dlopen support
323 --enable-win32-dll enable building dlls on win32 hosts
324 --help display this help and exit
325 --no-verify do not verify that HOST is a valid host type
326 -o, --output=FILE specify the output file [default=$default_ofile]
327 --quiet same as \`--silent'
328 --silent do not print informational messages
329 --srcdir=DIR find \`config.guess' in DIR
330 --version output version information and exit
331 --add-tag=TAG append an alternate configuration
332 --with-gcc assume that the GNU C compiler will be used
333 --with-gnu-ld assume that the C compiler uses the GNU linker
334 --prefer-pic try to use only PIC objects
335 --prefer-non-pic try to use only non-PIC objects
336 --disable-lock disable file locking
337 --cache-file=FILE configure cache file
339 LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
340 that provides basic libtool functionality.
342 HOST is the canonical host system name [default=guessed].
