Hi, I have just tried gcc-4.4.1 on AIX 5.3 and got the same linking error I previously reported in: http://gcc.gnu.org/ml/gcc-help/2009-05/msg00323.html which is: collect2: library libstdc++ -lsupc++ not found. I thought that a patch correcting the issue had been committed on GCC main branch (from Dave Korn or David Edelsohn) but it seems not so. Or am I doing something wrong ? Thanks a lot for your help.
