The maps file assumes you want to generate all these macros for each  
thing in the maps file.

If the C library does not define a GType for this enum, then either

1.  remove it from the maps file
2.  provide your own conversion function with this name
3.  provide your own GType mapping

Which one you use depends on how the enum is used.  If it's used as an  
object property, the C library really ought to have the GType.
