That is not a fix, that is sweeping the problem under the rug. As a somewhat dirty hack I added #if __MSP430X_LARGE__ #undef __SIZE_TYPE__ __extension__ typedef unsigned __int20 __SIZE_TYPE__; #endif to the start of the installed stddef.h, and that fixes the problem fine, for correct programs that do not forget to include <stddef.h> (directly or indirectly), anyway.
