The customary way of handling Postgres version differences at
compilation time has been something like
#include "catalog/catversion.h"
#if CATALOG_VERSION_NO >= 200804201
... new code ...
#else
... old code ...
#endif
Seems to me that would do just fine and you don't need autoconf help.
I concur with Alvaro's comment that you're probably wasting your time
to do anything touching snapmgr.h right now, but if you must ...
