Also gratulations from me.

Probably not surprising: With the patch GCC compiles fine (on
openSUSE/AMD64).
I also tested a couple of F95 and F77 non-TR15581 applications (among
them Wien2k, Fleur, Exciting, Octopus); compilation and running them was
ok. Some minor tests of allocatable elements in type, allocatable dummy
arguments and move_alloc work well, as do -std=f95 vs. -std=f2003.

If I saw it correctly, the third argument is gone with the lastest patch
by FX.
