We have this page:
http://trac.ffmpeg.org/wiki/Including%20FFmpeg%20headers%20in%20a%20C%2B%2B%20application

We could extend the page, probably rename it, add more comments about
using FFmpeg from C++ and link it from the README (which we should
rename DONTREADME so people would actually read it).

As it is the patch is half baked, because:

1. it is not written anywhere that examples can be directly converted
to C++ code
2. the preprocessor hack is only adopted in muxing.c, ignoring all the
other C examples.
