* c-exp.y (parse_number): Change high_bit to unsigned.

	* demangle.c:  Change all references to cfront to ARM, since the
	actual algorithm is the one specified in the Annotated Reference
	Manual.  This was confusing users into thinking that full cfront
	support was implemented.
	* dwarfread.c (CFRONT_PRODUCER):  Remove, was never really used.
	* eval.c (evaluate_subexp):  For STRUCTOP_PTR pass the arg type
	directly to lookup_struct_elt_type, which will do the
	dereferencing itself.
	* gdbtypes.c (lookup_struct_elt_type):  Expand comments.  Fix
	NULL dereferencing bug for unnamed structs, comment out
	questionable code.
