*Putting brown paper bag over my head*. Arg! Forget it, it was not
g++ that is buggy, it turned out that the biggest bug was sitting
*in front* of the computer...

I've "make clean"-ed the wrong sourcetree, so my pgadmin3-trunk tree
still contained some old object files built against 2.6.3...
I've now cleaned my tree, and am in the process of recompiling...

Sorry for the noise and confusion..

Interesting.. So "universal binaries" actually contain both i386 and ppc
code in one file? I've always though that universion apps just contain
two different binaries for both architectures (One in "MacOS", and one
in "MacOS86" or such...)

Hm.. I think that will need some work to "do the 
right thing" for universal binaries - Or have you already found a
solution for that?
