This comment seems unnecessary, given the code.

This seems like an internal detail, and so not interesting enough to
comment.

This branch seems pointless.

This comment seems unnecessary.

And ok(TRUE) does nothing, so there's no point in having it.

Does a program actually depend on this function crashing? If not, I
suspect it would be better to leave off this test entirely, or add
something like the following, as is done elsewhere in Wine tests:

if (0)
{
    /* crashes on Windows */
    ret = pRtlGetNtProductType(NULL);
}

Is this trace() really worth having? We already have too many...
