yes it is still a problem with the gcc that ships with openbsd 3.0.
with openbsd 2.8 (when i originally filed the bug report) they were using
"gcc version 2.95.3 20010112 (prerelease)", and with 3.0 it is now
"gcc version 2.95.3 20010125 (prerelease)"
Here is that same compilation unit being compiled under openbsd3.0/i386

I have some questions about your code - suggestions really, in the form of
direct orders. - T Farnon
