------- Comment #2 from pinskia at gcc dot gnu dot org 2009-12-20 03:41 ------- So we have:
extern wint_t __btowc_alias (int __c) __asm ("btowc"); extern __inline wint_t __attribute__ ((__nothrow__)) btowc (int __c) { return (__builtin_constant_p (__c) && __c >= '\0' && __c <= '\x7f' ? (wint_t) __c : __btowc_alias (__c)); } if (btowc ((-1)) != (0xffffffffu)) I don't know if what people expect this to happen really. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42440
