I have compiled and used MySQL with very old versions of gcc and with
systems where size_t is signed.  I don't think it would be hard to get
the current code to work on these systems.

The issue I have mainly with size_t for enum is that in some people's
mind it's not guaranteed to be unsigned and because of that it's not a
perfect choice.

Personally I prefer to use 'uint, ulong, ulonglong' or even
uint32 and uint32 instead of size_t for some objects.

For strings and objects sizes in memory I think that size_t is ok.
