non-ANSI bootstrap nits

[Alan Modra <alan at linuxcare dot com dot au>]

Hi,
  This fixes a couple of nits where functions are called with (possibly)
different sized args than expected.  Only a problem with non-ANSI
prototype capable compilers that happen to have `HOST_WIDEST_INT' a
different size to `int'.  Noticed when trying (unsuccessfully so far) to
bootstrap with the HPUX bundled cc.

	* cppexp.c (parse_charconst):  Change `mask' type to agree
	with parse_escape.
	* tree.c (build_index_type): Cast return of tree_low_cst to
	agree with type_hash_canon param.
	(build_range_type): Likewise.
