Waves compilation problem

[mathieu]

There are many questionable syntactic writing in SWAN that cause problem to ifort on ismaltx. See below a (partial) list in swmod1.F:

• version number 40.21 at end of line
  
• missing & at end of line for text over several lines
  
• author name jcw at end of line
  

I can give a diff file if deemed useful.

HGA: The problem here is that files with extention .f90 are compiled using free-form flag by default. This is very easily corrected by forcing SWAN to be compile with fixed-form flag. We just need to modify the make configuration files *.mk. Notice that ROMS follows extrictily the standard and can be compiled with either free-form or fixed-form flags.
