Update.
2001-11-26 Ulrich Drepper <drepper@redhat.com> * stdio-common/vfscanf.c: If incomplete nan of inf(inity) strings are found call conv_error and not input_error [PR libc/2669]. * math/bits/mathcalls.h: Mark ceil and floor as const. Reported by David Mosberger. 2001-11-21 Jim Meyering <meyering@lucent.com> * posix/regex.c (iswctype, mbrtowc, wcslen, wcscoll, wcrtomb) [_LIBC]: Define to be __-prefixed. Remove unnecessary duplication in `#ifdef _LIBC' blocks.

The GNU C library only supports one character of pushback---in other
words, it does not work to call @code{ungetc} twice without doing input
