Tim,
Working with the new Qt3 from svn, I have found 2 issues:
(1) It still needs to be patched for gcc-4.6 (see gcc46-arch.diff);
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.
and
(2) The link in src/include for src/inputmethod/qinputcontextfactory.h is missing
Fixed in SVN revision 191.
Tim
