internal compiler error

[David Covey <dnc at ruff dot gi dot alaska dot edu>]

Hello,
    I have been using egcs 1.0 for some months now without any problems
on a DEC Alpha/RedHat Linux (v.4.2) system. Today I encountered an error
in attempting to build the 'vis5d' application, specifically in building
the 'Mesa' graphics library. I upgraded the compiler to egcs-1.0.2 but
get the same error. The errors were 'internal compiler error' so I thought
I'd pass along the report. Details are attached below.
    Thanks for the support!
