From: Paul Jakma <paul@clubi.ie>
Subject: [zebra 19097] HAVE_ASM_TYPES does anyone know why lib/zebra.h has: #ifdef HAVE_ASM_TYPES_H #include <asm/types.h> #endif /* HAVE_ASM_TYPES_H */ There's no need for it that i can see (least not on linux) and it causes compile warnings. Is it needed? If so, why?
