Sure.

Just because it has historically been user32 that reported failure to load the driver doesn't mean it must remain so, at least to my way of thinking.  Why not just print out the diagnostics directly in gdi32 as each attempt to load a driver fails?
I figured it was that way for a reason, so I was trying to reduce noise 
in the case that fall-through drivers fail.  Even with making mac the 
first thing we try to load, it seemed that a valid use was setting by 
hand to, e.g., x11,mac, with working X11 libraries and DISPLAY unset.  
But yes, it's more complicated: I don't care where they're printed.  
(The same is true for the ERR->TRACE bits in the third chunk - I 
certainly don't mind them both staying ERRs, or WARNs.  I had 
interpreted the failure of those things differently until the point at 
which a window creation was attempted, but maybe that's wrong.)

Well, if something in Apple's code fails, it's still likely they'll 
print to the console, yes?  At any rate, I'm not attached to the error 
message.  As for whether to print errors in gdi32 or user32, I don't 
feel strongly about that personally, either, but I'm curious what others 
think.
