Hi Volker,

cmocka.c includes stdint.h before including cmocka.h, my patch does the
same for the other .c files which include cmocka.h. Apparently upstream
did not consider the use case of including cmocka.h directly.

Of course adding "#include <stdint.h>" directly to
third_party/cmocka/cmocka.h fixes the problem as well.

Regards, Bernd
