This was part of an unrelated message.

------- Start of forwarded message -------

It's the version that comes with cygnus b18. gcc version
cygnus-2.7.2.961023. I am reluctant to move to b19 because there seems
to be a bug in cmp whereby it sometimes reports identical binary files
as differing. I don't know the exact circumstances causing this, but
it only seems to happen several levels down into shell scripts. This
completely ruins my compiler test suites.

------- End of forwarded message -------

I took a quick look at diff/cmp.c, and it appears that it does not
open the file in binary mode.  That suggests that it be possible to
construct files which cmp would report as the same although they
actually differ.

I don't know why cmp would report files which are the same as
differing.  The bug report may not be correct.
