[PATCH] Problems with Cygwin mmap/munmap (mmap.cc) [correctly formatted]

[Kelley Cook]

All right Chris, I'll get to work on the copyright assignments ...

In the meantime, here is my first version of corrections, which just ignores
the problem entirely and is therefore extremely short (one line).  Hopefully
short enough to put something in place while the long process of legalness
is sorted out.

It, of course, doesn't fix any of the memory leaks, but it does allows GCC
2.97 to bootstrap by avoiding unmapping memory that might still be used.

	* mmap.cc (munmap): Check that mmap and munmap length match.
