--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That looks like a bug in gengtype-lex.l to me.
At least the
%{
#ifdef HOST_GENERATOR_FILE
#include "config.h"
#define GENERATOR_FILE 1
#else
#include "bconfig.h"
#endif
#include "system.h"
part shouldn't be in %{ ... } but %top{ ... } IMHO, config.h or bconfig.h needs
to be the first header, followed by system.h.
The reason it works on most other OSes is that e.g. glibc stdint.h has just
# if __WORDSIZE == 64
# define SIZE_MAX (18446744073709551615UL)
# else
# if __WORDSIZE32_SIZE_ULONG
# define SIZE_MAX (4294967295UL)
# else
# define SIZE_MAX (4294967295U)
# endif
# endif
and not like OpenBSD
#ifndef SIZE_MAX
#define SIZE_MAX UINTPTR_MAX
#endif
As stdint.h is a system header, warning about redefinition from the flex
provided
#define SIZE_MAX (~(size_t)0)
to the above ones isn't emitted.
