[Win95] vfork: No more processes



Congratulations to everyone on the release of B20.1.

Using Windows 95 and all versions of 'cygwin1.dll' (except the
first one that did not work on Windows 95), I have consistently
been getting page faults when building multiple subdirectories.
The build process never seems to stop at the same place. This
is happening with both the Cygnus version of make and make-3.77.

When Windows 95 forces me to close 'make' I get the bash
prompt back and I can restart make and go again.

I suspect either a bug in the fork process on Windows 95 or
a hardware problem that B19 failed to expose.

Any insights on what might be the cause of this will be
appreciated. Following is the information I have at hand.
This information is from just one occurrence that I picked
at random while running make with the debug flag.

MAKE caused an invalid page fault in
module KERNEL32.DLL at 0157:bff727f4.
