Re: N3322 functionality tests

Hi Lasse,

The multiplatform CI shows two test failures on mingw (that I can reproduce
locally):


FAIL: test-wmemcpy
==================

../../gltests/test-wmemcpy.c:31: assertion 's1 == NULL' failed
Stack trace:
0x45b14ea null_wmemcpy
	../../gltests/test-wmemcpy.c:31
0x45cd60b main
	../../gltests/test-wmemcpy.c:63
FAIL test-wmemcpy.exe (exit status: 1)

FAIL: test-wmemmove
===================

../../gltests/test-wmemmove.c:31: assertion 's1 == NULL' failed
Stack trace:
0x3a9e14ea null_wmemmove
	../../gltests/test-wmemmove.c:31
0x3a9fd60b main
	../../gltests/test-wmemmove.c:63
FAIL test-wmemmove.exe (exit status: 1)


They are probably due to the definition of wmemcpy and wmemmove as inline
functions (that redirect to memcpy and memmove, respectively) in mingw's
<wchar.h>.

How should we handle this? Just skip the tests #if defined __MINGW32__ ?
Or do you see something better?
