Thanks for the bug report and patch. I have one question (and I'd still like to do some testing before pushing): Isn't the '!' line a Fortran 90 comment, and doesn't that have to be written differently for pure Fortran 77? > See the attached patch where I also > added OpenMP flags for the Cray and NEC compilers. If you are happy with > this patch, please add Markus Geimer to THANKS, too. Yes, that part is quite obviously good (it has a near-zero chance of regressing anything!).
