[PATCH] Remove pa_char, pa_short_int, pa_u_short_int and pa_float


Hi!

Now that vfprintf always sets pa_int (resp. pa_double) instead of these
union members, we shouldn't read from them either.
Tested on ppc-linux.

2003-05-27  Jakub Jelinek  <jakub@redhat.com>

	* stdio-common/vfprintf.c (process_arg, process_string_arg): Use
	pa_int/pa_u_int instead of pa_short_int, pa_u_short_int and pa_char.
	* stdio-common/printf-parse.h (union printf_arg): Remove pa_char,
	pa_short_int, pa_u_short_int and pa_float.
