Thanks for taking the time to look at that Uros, and apologies for not getting back to you sooner.
With regards to your other question:
> So, is it necessary to define DEFAULT_PCC_STRUCT_RETURN ?
It’s not necessary, but a number of other i386 targets like GNU and NetBSD have it explicitly defined. I wasn’t sure if it was for legacy reasons or to document clearly the choice. I can prepare a patch to remove DEFAULT_PCC_STRUCT_RETURN from i386elf.h if you think it would be clearer not to explicitly define it.
