The same is true here.
I have no great pain with this as it is well documented how you
get a self contained build back.

That's right. The code explicitely requires pices from 2.1.4.

The define is protected by an #ifndef therefore you can add some elaborate
version testing to an imake configuration file.

Right. I would prefer to have this either in host.def or in a vendor
specific *def file, though.

However this does not answer my other question and it looks like 
nobody has ever looked into this. The Xserver module (and maybe
the other freetype libs) do require a symbol not exported to
the external ABI thru a header file.
Has anyone tried if this works better on a later freetype version?

Egbert.
