[Bug fortran/60751] Extra comma in WRITE statement not diagnosed

--- Comment #1 from Walter Spector <w6ws at earthlink dot net> ---
Simple test case:

program extracomma
  implicit none

  write (*,*), 1, 2, 3
end program

This compiles without error.

I notice that if I compile with -std=f95, it does diagnose this as a GNU
Extension.  My thoughts are that a warning message should be issued, rather
than quietly accepting the extension by default.
