re PR fortran/56224 (gfortran -fopenmp cannot find omp_lib.h)

2013-02-14  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/56224
	* gfortran.h (gfc_add_include_path):  Add boolean argument
	for warn.
	* scanner.c (gfc_add_include_path):  Pass along warn argument
	to add_path_to_list.
	* options.c (gfc_post_options):  Add true warn argument to
	gfc_add_include_path.
	(gfc_handle_module_path_options):  Likewise.
	(gfc_handle_option): Also gfc_add_include_path for intrinsic
	modules, without warning.
