I read your blog post and I'm afraid I don't see the point: you write some
code to tap into a pre-existing library that figures out what platform you
are on so that you can write out a 'config.h' that #define's the platform
you are on so that you can then use the C preprocessor to pick a particular
code path via conditional compilation.  Why go to all that bother?  Why not
just write code that writes out the path you want to take and link against
it?
