C++ compiler maximum number of classes

Question

In meta-programming number of classes grows quite fast. Is maximum number of classes modern compiler allows, for example g++, something to be concerned about?

Thank you

I'd guess this question is best answered by the standard published by the C++ committee. But looking at this place, I can't see any upper limit on the number of classes although there is minimum quantity limit on many items (saying at least the given number of items of each type should be supported by the compiler but that is not a binding limit). If your compiler can support these minimum limits, you should be OK.

But what factors would have the say on the upper limits on the number of classes kindles my academic curiosity. I'd be glad to know if a compiler guru can answer that.
