Building now 20130202 version (stage2 of bootstrap at this moment).

About building DJGPP libc:

Perhaps we could define something like __DJGPP_LIBC_BUILD__ and avoid including x86intrin.h
in is such macro is defined.

#ifndef __DJGPP_LIBC_BUILD__
#include <x86intrin.h>
#endif

There may be more similar situations in future, so we could solve them in the same way.

Other way (perhaps better) could be finding GCC own include directory and add it to include
directories

GCC_INCLUDE_DIR := $(shell $(CROSS_GCC) -print-file-name=include)

After that we could add -I$(GCC_INCLUDE_DIR) to the compiler options before DJGPP own include dir
