In the end we decided to develop a perl script to expand our one specific macro only. The problem with Doxygen was that, even with the tag EXPAND_ONLY_PREDEF, it expands all the #include. And we didn't want any other processing than just one macro. For our perl script I took inspiration from this http://www.cabaret.demon.co.uk/filepp/ which I recommend.
