I am getting the error from Intel C++ at the point of declaration of the compressed_pair specialization.
I've experimented some more, and found one bug in the current implementation:
If one of the templates arguments is both const and an empty class, then compressed_pair attempts to inherit from the const-class type which generates an error for Intel C++, but not strangely for VC++.
I've attached an updated version with some trivial (tested on all the compilers I have) fixes, does this fix your problem?
Yes, that does it, thanks. I'll check it in on your behalf.
BTW, at the risk of stating the obvious, compiler error messages really help when reporting issues (JM runs and ducks for cover!).
Okay, here's your next challenge. This is with the very latest Comeau alpha release compiler.
