Detect when multiple enum items map to same value

Question

Is there a compile-time way to detect / prevent duplicate values within a C/C++ enumeration?

The catch is that there are multiple items which are initialize

Answer 1

You could roll a more robust solution of defining enums using Boost.Preprocessor - wether its worth the time is a different matter.

If you are moving to C++ anyway, maybe the (proposed) Boost.Enum suits you (available via the Boost Vault).

Another approach might be to use something like gccxml (or more comfortably pygccxml) to identify candidates for manual inspection.
