Differences between 95 and NT would be proprietary information.
I fail to see why differences in the behavior of cygwin-compiled
executables would be Microsoft proprietary, though... At the very
least, I would expect someone to have an idea of what (programs,
operations, commands, source code, etc.), in general, tends to
"break" 95 while working fine under NT.

What causes the crash in the egcs testsuite? Which test? Why does
it break (if known)?

I suppose a better question would be: What C/C++ source has a
tendancy of segfaulting under 95, but working fine under NT?
I'd like to narrow down whether this is a problem with the
runtime under 95, or a problem with the OS itself. Either way,
if I know what source is "unsafe" under 95, I can try to re-write
my code to work safely under 95 as well as NT. But until I know
what issues to look out for, re-writing isn't an issue.
