                * util/misc.c: Include config.h.
                [!HAVE_MEMALIGN]: Do not include malloc.h.
                (grub_memalign): Use posix_memalign, if present. Then, use
                memalign, if present. Otherwise, emit an error.
        
                * util/grub-emu.c: Do not include malloc.h.
        
                * include/grub/util/misc.h: Include unistd.h. This is required 
for
                FreeBSD, because off_t is defined in unistd.h. Reported by 
Harley
                D. Eades III <address@hidden>.
        
                * configure.ac (AC_GNU_SOURCE): Added.
                (AC_CHECK_FUNCS): Check posix_memalign and memalign for the host
                type.
