Have you added something to the *_enums.defs file? Maybe it is badly
formed, or somehow strange.

I see this sometimes when I forget a bracket or quote somewhere in
the .hg file. Try to comment lines out until you see what triggers the
error.

It means that gmmproc tried to find a way to convert a
GtkRecentFilterFlags to a RecentFilterFlags. The _CONVERSION() macros in
tools/m4/convert_gtk.m4 tell it how to do this. You need to add one. Or
in this case, I think there is a special macro there fore enums.
