2016q1 update can not be built on FreeBSD: something wrong with stdint.h

I'm maintainer of gcc-arm-embedded port for FreeBSD.

All previous versions didn't have any problems to be built on FreeBSD with all instructions from build-toolchain.sh script. gcc-arm-none-eabi-5_2-2015q4-20151219 could be built flawlessly, for example. I've converted script to Makefile, but it doesn't matter, as all steps are the same.

But latest update gcc-arm-none-eabi-5_3-2016q1-20160330 fails to built on first gcc stage, as there are some problems with gcc-provided "stdint.h". Here is compiler command line and error from it (I've replaced looooooong path prefixes with variables from build-toolchain.sh):

===============================

Host system have stdint.h (as /usr/include/stdint.h), but looks like cross-gcc is instructed to not use host headers files (which is right), but provided file ("$BUILDDIR_NATIVE/gcc/include/stdint.h") does something wrong!

stdint.h in question ("$BUILDDIR_NATIVE/gcc/include/stdint.h") looks like this:

===============================
#ifndef _GCC_WRAP_STDINT_H
#if __STDC_HOSTED__
# if defined __cplusplus && __cplusplus >= 201103L
# undef __STDC_LIMIT_MACROS
# define __STDC_LIMIT_MACROS
# undef __STDC_CONSTANT_MACROS
# define __STDC_CONSTANT_MACROS
# endif
# include_next <stdint.h>
#else
# include "stdint-gcc.h"
#endif
#define _GCC_WRAP_STDINT_H
#endif
