I have updated the patch to include saving the pad size in the expressions type 
specification so that calculated lengths used later can be adjusted to avoid 
spurious warnings.

Test case attached.  I expect to revise this to handle platforms that may have 
different endian-ness.

Regression tested on i686-Gnu-linux.

OK for trunk.

	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.
