Yeah, i've got a halfworking GCC 2.7.2p. I had got lot of problems with it,
and still have some.
One problem is that the patch comes from the unix world, with directory
names like GCC-2.7.2p but it's fixed now.
The another and bigger problem is, that the patched and recompiled DJGPP is
unstable. Under MS-DOS (using the CWSDPMI) compilation allways fails
(SIGSEGV) when I try to compile with the -mpentium flag. Within a Win95 DOS
there are no problems, just somethimes it crashes with a DPMI error:can't
allocate descriptor... message. I think the patched version runs out of
free descriptors, I know that the pentium optimizator (the rescheduler)
uses lot of memory. Maybe that's the problem, but unfortunately I've got no
time to play 'round now.

So it means I've got the binaries, but they are really unstable, and I
don't want to distibute them in this state. The project I'm involved in
will finish within a month, and I plan to make a fully workable pentium
"addon" to the DJGPP, and of course i'll share it if I've got it.
