re PR fortran/43217 (Output of Hollerith constants which are not a multiple of 4 bytes)

Browse Source 
2010-08-27  Jerry DeLisle  <jvdelisle@gcc.gnu.org>

	PR fortran/43217
	* primary.c (match_hollerith_constant): Calculate padding needed to
	fill default integer and allocate string for that size.  Set pad bytes
	to ' '.
	* gfortran.h: Add hollerith pad value to type spec union.
	* data.c (create_character_initializer): Fix spelling of function name.
	Use hollerith pad value to calculate length.
	* arith.c (hollerith2representation); Use hollerith pad value to
	calculate length.
