Thanks! I'll wait for your additional testing, of course.

No, although it wouldn't be difficult. The problem is that stage2
closes soon, and I've integrated most of the things I thought nice to
implement, except one a tricky one: merging of function decls, which
is proving to be rather tricky. I think, from now on, I'll be focusing
on that one to get it before stage2 closes. I'm not sure I'll make it,
though :(

Probably because we call a function with a pointer to a somewhere
(I/O?) which cannot lead to modification according to Fortran rules,
but we don't correctly give this information to the middle-end. There
are several such missed-optimizations throughout the front-end, I
think.
