Patch: hpux warnings removal

[RDBrown at mira dot net]

Building the 20010324 snapshot on hpux11, gdb still hangs starting the
process. I think the 0320 snapshot also behaved this way on hpux10.20,
built with either gcc-2.95.2 or the vendor compiler.
The enclosed removes trigraph warnings etc.

(for gdb/ChangeLog)
2001-03-26  Rodney Brown  <RodneyBrown@mynd.com>

	* config/pa/tm-hppa.h: Remove trigraph.
	* hp-symtab-read.c (hpread_type_translate): Provide return value.
	(hpread_read_struct_type): Remove trigraph. Add parameter in `warning'.
	(hpread_read_array_type): Provide return value.
	(hpread_type_lookup): Avoid ambiguous `else'. Provide return value.
	* hppa-tdep.c (initialize_hp_cxx_exception_support): Remove trigraph.
