    You should not need to rely on the macro name to parse this. A structure
of the forms "id( expression-list);" could be parsed as a function
declaration returning int (well, that's how I would do it). As I said this
kind of macro is not specific to cppunit.

    I certainly won't remove those because a text editor can not ident
correctly ;-)

    Which is not portable. It relies on a specific build system, as well as
a shell environment. Beginners would  probably run away ;-). Also, this slow
down the build process. I like being able to run my test plug-in a a few
seconds ;-)

    You might want to look up project cuppa
(http://sourceforge.jp/projects/cuppa/) which (I believe) provides a
portable implementation to do that.
