Guys,
I have finally gotten a few minutes to dive back into Trinity. To my
chagrin,
we have Arch has bumped from gcc 4.5 to gcc 4.6. I am having problems
building
Qt3. Adding to the difficulty, the Qt3 build script for Arch has been
through a
number of changes lately and I haven't had time to verify the new build
script
under gcc 4.5 before the jump to gcc 4.6. So I am working to understand
whether
this build failure is gcc related or if it is a normal screw-up on my end.
The build is failing in the middle of the build, so this leads me to think
this might be gcc related.  If anybody can look at the error and determine
whether this is a gcc issue or not, I would greatly appreciate it. I think
what
I'll do is drop back to a build script that I know was working on gcc 4.5
and
confirm, but in the interim, I thought I would post the error in hope
somebody
else had seen this already. What does this error look like to the masters?:

I'll go try an older build script that used qt-x11-free-3.3.8 instead of
qt-x11-free-3.3.8b. I'll report back :p
There should be a patch at openSUSE for gcc46
