Thanks for the notes on this. There's quite a bit about the whole  
font-finding and management that I'd like to tidy up, and certainly  
getting rid of these messages is part of it; I just haven't had time  
to work on it yet. So your tracking of where they're generated is a  
useful pointer.

Another one that's pretty annoying is that xdvipdfmx will fail to  
load a TrueType font if the extension is .TTF rather than .ttf (which  
I've seen on some fonts from the Windows world); this happens, IIRC,  
because after the font has been found by fontconfig, the name gets  
sent through kpathsearch, which decides it isn't valid for a TT font,  
and returns a failure. This whole code path needs to be re-designed,  
as full paths from FC don't need to be sent through the path-search  
like simple filenames from the old .map.

Same thing probably applies to other extensions like .OTF and .PFB; I  
haven't encountered those, but they could show up, especially on case- 
insensitive systems.
