gcc-20010312 build fails on cygwin 1.1.8

[Kelley Cook]

After much gnashing of teeth stepping through with the debugger looking for 
the mistake in cpp0, I was just clued into the fact that it was (again) due 
to a mmap bug introduced in cygwin 1.1.8.

Grab a recent snapshot of cygwin1.dll and GCC 3.x will work fine.  They are 
available at ftp://ftp.freesoftware.com/pub/sourceware/cygwin/snapshots/
