Is there any guarantee that the configuration files will work with a C compiler or a C++ compiler in C mode ? Is there anything in the configuration files which is C++ specific ?
Almost certainly :-(
I am working on bringing my variadic macro data library into Boost PP, and I wanted to use the BOOST_NO_VARIADIC_MACROS in config, but Paul Mensonides was concerned that Boost PP should work with a C compiler and that config could have something that is C++ specific, and therefore be unusable for Boost PP. I would rather not reduplicate the logic of BOOST_NO_VARIADIC_MACROS in Boost PP, even though I was the one to add it to config, because it puts the same code in two different places.
We could try and patch Boost.Config to make it C compatible I guess... not sure how much work it would be though? John.
