Agreed, I suppose.  The problem is getting enough heads together to figure
everything out.  I don't think there is a "generic" Fortran compiler for
Suns.  I think it's always been an add-on.

I only changed the comment from "why fixed?" to explain to someone without
the compiler man page available just what the -fixed flag is.

I believe "f77" on Suns really runs f90 with appropriate flags.

After reading the info about the -R flag in the f90 man page I'm not sure,
although I think I tried getting rid of it, but that failed.  I tweaked what
is there a little.  It didn't handle the case where LD_RUN_PATH was not
defined.  I'll try disabling it again and see what happens.
