[Tfug] Changing default suffix rules for "make"

[Terence Rudkin]

Not a direct anser to the question.  When I am faced with needing to
make a change to a make file I first want to leanr what it already does.

	make -p -n -f <makefile>   

This will let you know what it knows.  Likly you will find a fortran
rule based on a different extention.   Find it from the output from the
above command.  Then find it in the makefile copy it and paste with the
other extention.
