[fortran, patch] IEEE intrinsic modules (ping)

And this is not all the testsuite, but only ieee_1.F90. After a long chase, it turns out it’s because it has a dg-options, which overrides my IEEE options in ieee.exp. This is because I used dg-options when I should have used dg-additional-options (phew!).

Attached is an updated test gcc/testsuite/gfortran.dg/ieee/ieee_1.F90, please check that it also fixes the spurious errors with non-installed module files.

I concur with your diagnosis. I’ve fixed this, and full new patch is attached (including regenerated files).

I’ll wait a few more days to commit, so others can comment/review and I am sure to be around if there is fallout.

Thanks again for your help!
