gcc-2.9.5 and dgux

[Doug Veldhuisen <dveldhui at redats dot bartlesville dot redapump dot slb dot com>]

I am writing this to ask for help in trying to get gcc-2.9.5 to compile  
on my Intel based dgux system.

This is as i indicated an Intel  DGUX R4.20 MU05 system.  

I tried using the gcc-2.95.2 distribution from gcc.gnu.org using the
following configure command:

./configure --program-suffix=-2.95.2 --prefix=/usr/local/gcc

The configure makes it all the way through with no errors. Next I
try to do a gnumake bootstrap.  This goes for a while until it gets the
following:

--omitted alot of the list--

_floatditf
__gcc_gcmp
_varargs
__dummy
_eprintf

gnumake[1]: Leaving directory '/home/dveldhui/gcc-2.95.2/gcc'
gnumake: *** [bootstrap] Error 2 


I looked thru the mailing lists and found a couple of instances of
problems with dgux and some necessary patches but they seemed to refer
to earlier releases.

I believe the release of c compiler is: 
	gcc version 2.7.2 (ix86 DG/ux, DG-2.7.2.9, Feb  3 1998)

Should I try to find the 2.7.2 release and try to compile for dgux?
Has anyone attempted to compile and use any release higher then 2.7?
Or is trying to get a C++ compiler on this system a hopeless task?

Please advise!
Thanks in advance
