Hi Steve,

Sorry to hear about your woes.  I don't have a fix for you, unfortunately,
but perhaps an idea.  You may be able to glean some information by looking
at the output of the preprocessor, which gets emitted to the compiler.  That
might give you a hint about what is defined (and what ought to be defined).

The gcc option for that, IIRC, is "-E".

Pete
