Hi,
This was causing my build of gcc to fail.
File winsup/cygwin/mmap.cc version 1.86 (and earlier) function munmap
when unmapping a 64K record, passes the wrong parameters to fhandler_base::munmap,
passing the function parameter address/length instead of a block local version.
This patch explains it all.
