! F95: 14.1.2.1:
! "A common block name in a scoping unit also may be the name of any local
! entity other than a named constant, intrinsic procedure, or a local variable
! that is also an external function in a function subprogram."
!
! F2003: 16.2.1
! "A name that identifies a common block in a scoping unit shall not be used
! to identify a constant or an intrinsic procedure in that scoping unit. If
! a local identifier is also the name of a common block, the appearance of
! that name in any context other than as a common block name in a COMMON
! or SAVE statement is an appearance of the local identifier."
Currently, valid Fortran 2003 programs are therefore rejected. The check
happens very early in the match.c's gfc_match_common ("Symbol '%s' at %C is
already an external symbol that is not COMMON").
