I downloaded the FITS package, and it's worse than I thought. Please
don't unfix gfortran. This is valid fixed-form Fortran.

If I understand correctly, you want to change gfortran to parse a leading
tab as 5 spaces if it is followed by digit; otherwise, the leading tab is
parsed as 6 spaces. OK, change the above program by replacing the 1 in
column 5 to 'd'. This is again a valid fixed-form code. Now, replace the
leading spaces with a tab. Do you expand the leading tab by 5 or 6 spaces?
Seriously, the FITS code is invalid.
