Well, your changes completely broke FreeType, since the font drivers
didn't return FT_Err_Unknown_File_Format anymore when they were handed
a stream to a font file they cannot handle.

I've just commited a fix, where all parts of FreeType that looked at
the error code now use the new macro FT_ERROR_BASE() (defined in
"fttypes.h") which now returns the module-less error code.
 
However, since we're going to release 2.0.4 really soon now due
to the transformation bug, I'd prefer to undefine
FT_CONFIG_OPTION_USE_MODULE_ERRORS for now..

Actually, since your changes break _source_ compatibility with
2.0.3 for applications that #include FT_ERRORS_H to generate
error messages (e.g. Pango), it may be a good idea to get them
out until 2.1.. ??

Good idea, please do it !-)
