gfortran to gfc comparison using gfortran testsuite

Hi,

While I agree with the global tone of the message, here is a point I don't 
agree with:

Well, I can quote at least a few areas where bugs are blocking many 
real-life codes:

   -- modules: gfortran is a bit weak on that (see for example PR 16861 and 
the number of  Cc: added to it)
   -- namelists: this may get better with the proposed patches
   -- arrays: ubound and forall are buggy in some cases, and there are many 
bugs filed with code like "a(/4,1,2/)".

Each Fortran programmer would probably have his own similar (but different) 
list... Yes, gfortran is getting better and better, and yes, it can already 
be used for small codes using simple language features (which is a very good 
thing). But real-life complex codes are a bit out of reach right now.
