IMO: Nonono.. VM should be compileable by any standard compliant C compiler.
In presence of JIT it makes no sense to produce non-portable C code,
which works only under special compiler.
And then we don't need to maintain this info.
For OpenDBX is another story, because you are linking with specific
version of library, which API might change.
But for compiling stuff.. i'd prefer to not mess with it.

For example, in SqueakDBX, in the OpenDBX class (which is the class that does the binding with FFI to OpenDBX) I have a class method called expectedOpenDBXVersion which is something like.
