Thomas Koenig 18fe404fbc re PR fortran/30814 (non-conforming array sizes in PACK should raise an error)
2007-07-24  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/30814
	* trans-decl.c (generate_function_code):  Add argument
	for flag_bounds_check to the array for set_options.
	* invoke.texi:  Mention that some checks require
	-fbounds-check to be set during compilation of the
	main program.

2007-07-24  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/30814
	* libgfortran.h:  Add bounds_check to compile_options_t.
	* runtime/compile_options.c (set_options):  Add handling
	of compile_options.bounds_check.
	* intrinsics/pack_generic.c (pack_internal):  Also determine
	the number of elements if compile_options.bounds_check is
	true.  Raise runtime error if a different array shape is
	detected.

2007-07-24  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/30814
	* gfortran.dg/pack_bounds_1.f90:  New test case.
