gcc bug on solaris 2.7?

[Satish Balay <balay at mcs dot anl dot gov>]

GCC developers,

I have the following report to file regarding gcc-2.95 on solaris 2.7.
I can reproduce the same problem with older versions of egcs(1.1) on
this machine. However everything works fine on a solaris 2.6 machine.

Don't know if this is a gcc bug or solaris-2.7 bug. I've tared up
the source files, including the intermediate files, and the output
from the options "-v --save-temps"  in make.log in this tar file.

Thanks,
Satish
