* mdebugread.c (handle_psymbol_enumerators, parse_symbol):

Browse Source 
Recognize enums from alpha cc -migrate.
	(upgrade_type):  Pass correct fd to parse_symbol when parsing
	the index type of an array.
	(parse_procedure, parse_lines, psymtab_to_symtab_1):  Handle
	unsorted procedure descriptors from Irix 5.x and Alpha OSF/1-3.x
	shared libraries. Use CORE_ADDR instead of `unsigned long' in
	procedure descriptor address computations.

	* symtab.c (decode_line_1):  Prevent accidental strchr match
	of a null character with the terminating null character of
	gdb_completer_quote_characters.
	(cplusplus_hint):  Make sure that only a single quote is printed
	in the hint message.
