them in the pst.
	* mdebugread.c (handle_psymbol_enumerators):  New function to enter
	the enumerators of an ecoff enum into the partial symbol table.
	* mdebugread.c (parse_partial_symbols):  Call it.
	* symfile.c (reread_symbols):  Initialize objfile->*_psymbols.next.
	* symmisc.c (dump_psymtab):  Fix typo, clean up output of section
	offsets. Cast psymtab->read_symtab to PTR before passing it to
	gdb_print_address.
	* i386-tdep.c (i386_skip_prologue):  Skip over instructions that
	set up the global offset table pointer in pic compiled code.
	* config/mips/tm-mips.h (FIX_CALL_DUMMY):  For big endian targets,
	error() on TYPE_CODE_FLT arguments whose size is greater than 8,
	swap all other TYPE_CODE_FLT arguments as mips_push_arguments
	ensures that floats are promoted to doubles before they are pushed
	on the stack.
