[patch, fortran] Fix PR35779 + some cleanup

[Daniel Franke]

Hi all.

Attached patch is mostly cleanup, the actual fix is in array.c 
(match_array_list), where the gfc_init_expr_flag needed to be passed on to 
generate a sensible error message.


gcc/fortran/:
2010-05-13  Daniel Franke  <franke.daniel@gmail.com>

	PR fortran/35779
	* intrinsic.c (gfc_init_expr): Renamed to gfc_init_expr_flag.
	Updated all usages.
	* expr.c (init_flag): Removed; use gfc_init_expr_flag everywhere.
	* array.c (match_array_list): Pass on gfc_init_expr_flag when matching
	iterators.

gcc/testsuite/:
2010-05-13  Daniel Franke  <franke.daniel@gmail.com>

	PR fortran/35779
	* gfortran.dg/initialization_25.f90: New.


Regression tested on i686-pc-linux-gnu.
Ok for trunk?

	Daniel
