I testetd with gpc-20010317

perhaps we should have p/diffs/gcc-2.95.3.diff where this is fixed

I think this renaming is understandable to avoid having executable with
the same name (cpp.$exeext) in 2 directories. I have seen related trouble
with DJGPP port of gcc-2.95.X (before 2.95.3) and avoided it by leaving
$prefix/bin/cpp.exe out of gcc295Xb.zip.

Yes. I tried. I run into some trouble when GPC_FOR_TARGET was not
passed from top level make to one in gcc subdirectory as ./xgpc -B./
is wring for Canadian crosses of course. As result make fails in
gcc/p/rts. I added definition of GPC_FOR_TARGET in t op level makefile
and passing it make in subdirectories.

If You want -mno-bnu210 to be usefull at all, You should use
binutils-2.8.1 or 2.9.1. For gcc-2.95.3 I made -mbnu210 the default
and added warning when -mnu-bnu210 is being used.
Now we have one more trouble with DJGPP port of gcc-2.95.3:
-gcoff seems to be broken
Unfortunatelly it was not detected before uploading files to
ftp.delorie.com. Otherwise I should have to consider it as showstopper ...
