Yes, I was waiting for that patch to stabilize (actually, I was originally hoping someone who has access to gcc4.6 could handle patching the Qt3 SVN but I will settle for a working patch that I can apply). If it is stable and working now please let me know and I will patch the Qt3 SVN immediately.
SUSE hav a good patch:
https://build.opensuse.org/package/view_file?file=gcc46.diff&package=qt3...
debian also, but debian do not fix the call on fntions.. only added the headers.
