I don't think that's it. That source is for `wbuild', which is used
only under X. Also, it's used only in the process of building MrEd, and
it should only be used when explicitly enabled through `configure'.

The error message is put in that file by `flex', though. Whatever is
printing the message is apparently also implemented using `flex'.
