If a feature remains in N minor versions the programmer would have to
put in N compatable-with macros to enable it. They would also have to
update the code every time a new minor version comes out (or just
predict a number of minor versions into the future and put in a bunch of
calls to this).
An "at least" macro can cover the N minor versions with only two calls,
one to check that it is at least the version the feature appeared in,
and another to check it is not at least the version the feature
disappeared in.
Please change AT_LEAST to work as people expect, and don't bother with
this COMPATIBLE_WITH idea. At least rename it as "MAJOR_MINOR_EQUALS" or
something clearly saying what it does.

Hi,
The macro should really be called WESTON_VERSION_COMPATIBLE_WITH() -
it's done that way specifically to allow breaking API/ABI at least
every minor release.
