configure finds out that cygwins mmap is broken and does not include <sys/mmap.h>

configure finds out that cygwin supports mprotect and defines HAVE_MPROTECT and HAVE_COMPATIBLE_MPROTECT

The compilation breaks in kaffe/kaffe/kaffevm/mem/gc-mem.c complaining the PROT_READ, PROT_WRITE... defines doesn't exist

PROT_READ and friends are defined in <sys/mman.h> which are not included because mmap is broken according to configure.
