That's interesting. I would expect an error regardless of version. I used an old 4.5.1 gcc that I had laying around (from denx, iirc). I'll find a newer one and try it. Either way, it seems to me that we should remove the duplicate definitions. Do you agree? Thanks, Mark -- ^ permalink raw reply [flat|nested] 9+ messages in thread

It might be a bug in your specific version of GCC since I can't replicate it with this dumb test case: #include <stdio.h> typedef unsigned int u32; typedef u32 uint32_t; typedef u32 uint32_t; int main(void) { uint32_t test =3D 0; printf("%u\n", test); return 0; } Does that result in an error? > Either way, it seems to me that we should remove the duplicate definition= s. > Do you agree? It wouldn't hurt to remove those definitions from libfdt_env.h. That file includes types.h directly anyway so there's not much point in them being there.
