This patch eliminates the "compatibility defines" _IO_UNIFIED_JUMPTABLES (always defined to 1, used in a number of #ifs which are therefore always false), _STDIO_USES_IOSTREAM (unused), __HAVE_COLUMN (unused), _IO_BE (replaced with __glibc_unlikely), and yet another redundant definition of EOF. Installed stripped libraries are unchanged by this patch. * libio/libio.h (_IO_UNIFIED_JUMPTABLES, _STDIO_USES_IOSTREAM) (__HAVE_COLUMN, _IO_BE): Don't define. (_IO_peekc_unlocked, _IO_getwc_unlocked, _IO_putwc_unlocked) (_IO_fwide_maybe_incompatible): Use __glibc_unlikely. * libio/libioP.h (EOF): Don't define. * libio/iofdopen.c, libio/iofopen.c, libio/iopopen.c * libio/iovdprintf.c, libio/oldiofdopen.c, libio/oldiofopen.c * libio/oldiopopen.c, debug/vdprintf_chk.c: Remove #if block testing _IO_UNIFIED_JUMPTABLES.
