Internal compiler error 373

Thu Feb 10 08:45:00 GMT 2000

Hello,

we've managed to trigger an "Internal compiler error 373" in egcs.
Criticality is low, as the error is triggered by invalid input
that is easy to fix -- but it took a while of staring at the code
to see the offending typo.

Here come the details:

Command line: 
-------------
avrchoti@frqmei5ux:(186)% egcc -v --save-temps foo.cpp
