Draft patch for the main issue and for the -std=f2003/f2008 diagnostic

The regression is caused by:

        PR fortran/46100
        * expr.c (gfc_check_vardef_context): Treat pointer functions

Attached is a draft patch for this issue and for the -std=f2003/f2008
diagnostic for comment 7 (cf. comment 8).

Using -std=f95, the test case in comment 7 segfaults; I have not checked
whether it is due to using an old gfortran (Rev. 165749) - nor whether it is a
regression.  This issue is tracked in PR 48776.
