Hi all,

here's a small and straight-forward patch for PR 22552 that adds a new
warning flag -Wimplicit-procedure for procedures that are called but
never explicitly declared.  The difference between -Wimplicit-interface
is that this option does not trigger when a procedure is declared
EXTERNAL but still does not have an interface.  This is useful for
legacy code, see the PR at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22552.

Additionally, this is the first "half" of my RFC at
http://gcc.gnu.org/ml/fortran/2009-12/msg00131.html, with Tobias'
proposed documentation change.

No regressions on GNU/Linux-x86-32. Ok for trunk?

Yes, OK, thanks for the patch.

Jerry
