Comment (by sean@…):

 The page you linked to,
 http://www.microscopy.cen.dtu.dk/computing/fortran/index.html, actually
 points out that gfortran from the R project hosted at AT&T is the one that
 supports the -arch flag. All GNU gcc compilers do not support the -arch
 flag. Be careful with gfortran from R because it is based on gfortran-4.2
 but that version of fortran is horribly riddled with bugs.
