Like I said, it could use Grep, but first it wants to determine what to 
search for (the "symbol"), and that's normally the "current tag", in 
buffers supported by Semantic.

Regarding Grep, though, there's no entry for Fortran in 
semantic-symref-filepattern-alist.

If you're using the current master (or can install it), you could try 
M-x xref-find-regexp instead. Or M-x xref-find-references.

This is from macro-expansion of `with-syntax-table'. As you can see, the 
argument is semantic-lex-syntax-table, which is apparently nil.

^ That's the function, inside which you should be looking.
