Was that fixed with John's commit?

I think so.  I believe this was left open because the patch wasn't
back ported.

I could confirm but that would take awhile.

Just for the record, I've attached my last version of a change to do this.
There was some discussion of this in the following thread:
http://gcc.gnu.org/ml/fortran/2008-04/msg00000.html

I ran out of time to work on it when the new register allocator was added
and the hppa port broke.

The solution to this issue would be to detect a broken strtod() (or strtof() or
strtold()) in libgfortran configury, and write a wrapper checking for
infinities and nans before calling the system's strtod().

Very low priority issue because HP-UX 10 is probably not that common any more
(HP-UX 11 was released 12 years ago), unless some other target is affected.
