Its used for
#define LIBAVCODEC_IDENT        "Lavc" AV_STRINGIFY(LIBAVCODEC_VERSION)
using snprintf() would make the code bigger.

My oppinion is still that the original was best, it was claimed that people
broke versions often but noone managed to point to more than a single
case where that happened and it was fixed quickly ...
If we really must use some tricks to force the versions to be equal
jeff downs solution looks like the best so far.
But i still prefer to just revert ...
