Yes, if the versions are compatible, and if the version is recorded in
a field in the returned context structure, then will even be simpler to just
return the highest version compatible, than my suggestion of having gdb
try both v1 and fallback to v0, which can be left for when we decide to make
a vN+1 that is not compatible with vN.  This is just like duck typing.
