Update.
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. 2003-05-26 Jakub Jelinek <jakub@redhat.com> * libio/strops.c (_IO_str_init_static): Change into a wrapper around _IO_str_init_static_internal. (_IO_str_init_static_internal): Moved from _IO_str_init_static, change size argument to _IO_size_t, don't limit sprintf to 64M. (_IO_str_init_readonly): Call _IO_str_init_static_internal. * libio/wstrops.c (_IO_wstr_init_static): Change size argument to _IO_size_t, don't limit swprintf to 256M. (_IO_wstr_init_readonly): Remove. * libio/libioP.h (_IO_str_init_static_internal, _IO_wstr_init_static): Adjust prototypes. (_IO_wstr_init_readonly): Remove prototype. * libio/iovsprintf.c (_IO_vsprintf): Use _IO_str_init_static_internal instead of INTUSE(_IO_str_init_static). * libio/iovsscanf.c (_IO_vsscanf): Likewise. * libio/memstream.c (open_memstream): Likewise. * libio/obprintf.c (_IO_obstack_vfprintf): Likewise. * libio/vasprintf.c (_IO_vasprintf): Likewise. * libio/vsnprintf.c (_IO_vsnprintf): Likewise. * stdio-common/tst-sprintf.c (main): Add new test.
