Thank you. We could decide to add them to the default Makefile
(i.e. to flags.guess) but I think it is better not to use them and fix 
the warnings (i.e. fold the lines in the source code) instead to make 
sure we fully comply with the F90 standard;

otherwise the same problems (truncated lines) could occur on other 
machines with other compilers (NAG, Portland...) in the future.
