[Bug fortran/22552] New: Would like warning when an undeclared function is called

["schnetter at aei dot mpg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

It would be nice to have an option for gfortran that emits a warning when an 
undeclared function or subroutine is called.  This would be similar to 
-Wimplicit-interface, except that this new warning would also accept 
non-explicit interfaces.  For example, the fragment 
 
external a 
call a 
 
leads to a warning with -Wimplicit-interface, but I would like to get no 
warning for this construct.
