--- Comment #5 from David Edelsohn <dje at gcc dot gnu.org> 2011-01-06 18:55:20 UTC --- (In reply to comment #4) > David, does GCC 4.5.x build on AIX? GCC 4.5 libgfortran builds on AIX 5.3, but not AIX 6.1. GCC 4.4 libgfortran built on both, so this is a regression, but I had not noticed the regression on AIX 6.1.
