It might be unobtrusive but there are very many config header files in which one would have to do that. Even doing it just for each compiler's header file would mean that each compiler would have to be tested which config supports. I do not think we even have every compiler which config supports being tested regularly, but I may be wrong.
True enough, but there weren't many changes required: try SVN Trunk now, Boost.Config should compile in C mode as well as C++ mode now. Tested locally with msvc, gcc (all the versions I could find!), intel and sun. I've also added a C-language test case, and manually inspected the compiler and platform config files for C++ specific code. Lets see how that works out...
I have some more patches. Do I attach them here or send them to you ?
Either is fine. John.
