Good choice! :)

I suggested looking how it's done at the 'configure' of Scalaris.

Its code is here: http://scalaris.googlecode.com/svn/trunk/configure

Search for e.g. gb_tree() or DIALYZER to see how to write (portions of) 
a configure script that allows to generate appropriate defines for 
various types that have become built-ins or changed status between 
different OTP versions.
