317 --build configure for building on BUILD [BUILD=HOST]
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].

2816 # By default, configure uses ./config.cache as the cache file,
2817 # creating it if it does not exist already. You can give configure
2818 # the --cache-file=FILE option to use a different cache file; that is
2819 # what configure does when it calls configure scripts in
2820 # subdirectories, so they share the cache.
2821 # Giving --cache-file=/dev/null disables caching, for debugging configure.
2822 # config.status only pays attention to the cache file if you give it the
2823 # --recheck option to rerun configure.
2826 # The following way of writing the cache mishandles newlines in values,
2827 # but we know of no workaround that is simple, portable, and efficient.
2828 # So, don't put newlines in cache variables' values.
2829 # Ultrix sh set writes to stderr and can't be redirected directly,
2830 # and sets the high bit in the cache file unless we assign to the vars.
