Sorry to answer my own question but I just downloaded the stock gcc 2.95.3
sources and the bug is indeed there, so while it got fixed in the svn repo
in 1999 apparently the fix never made it into a gcc2.95.x release.

This question still remains though, perhaps I can back-port a fix from the
gcc sources. Although, I was expecting to see the bug fixed after 2001, not
in 1999. Since this is gcc2 and binary compatibility is critical here, I'd
like someone with more experience in this area to check out the code and
see if there is anything I can do to fix this.
