I've seen the thread here (I don't know who the doc writer is, but I 
don't think they monitor these lists that closely), but I'm not too 
sure what to do about it. I could squelch the NULL access error, but 
it's not clear to me that silently letting the function access NULL 
is OK.  FntDefineFont is testing a value; I have no idea what's at 
NULL or which way the test will go.  I don't even know if the test 
will change from device to device, since the contents of NULL are 
undefined.  Therefore, it's not clear to me that silently letting it 
access NULL is what we want.
