The tables consist of code like:
... offsetof(S,m) ...
since the Felix compiler does not know the size or layout
of C structures or types. I would say that is is much
faster than a bitmap (but uses up to 64 times more memory on
a 64 bit machine so maybe not .. :)

Yup, that's a standard technique, but it worries me.
Both thread safety and dynamic loading are issues.
I definitely do NOT trust dynamic loaders to do
initialisation or access shared variables.

Well sure, it is not only Open Source, liberal licence
(like boost), but very open for developers to contribute :)
So anything from advice to code is welcome!
