Something like:

Or, given the proposed rewrite of the config stuff have the macro defined to 0 for all compilers except gcc and use as #if BOOST_PP_HAS_WARNINGS
I don't think this will help, because the preprocessor seems to scan the whole file.
Interesting. We've used that solution for ever with LyX and I never had a problem with my (admittedly old) version of DEC's cxx. That machine is now history however. Presumably, therefore, the solution is to define BOOST_WARNING(text) which expands to nothing with all compilers except gcc for which it expands to #warning text. Angus
