intprops.h, xalloc-oversized.h: work with gcc 7 In gcc 6, __builtin_add_overflow, __builtin_sub_overflow and __builtin_mul_overflow each accept a NULL pointer as the third argument. However in gcc 7, that is no longer accepted. Instead, one must use the "_p"-suffixed names, with which, the third parameter is no longer a pointer. * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): Correct the definition: not true for gcc 7 and subsequent. (_GL_HAS_BUILTIN_OVERFLOW_P): Define. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Provide new definitions for gcc 7 and subsequent. * lib/xalloc-oversized.h (xalloc_oversized): Provide a definition that works with gcc-7.
