[fpc-pascal] InterLockedIncrement wrapping etc.

[Mark Morgan Lloyd]

Looking at 2.7.1 for i386, InterLockedIncrement() appears to be take a 
signed 32-bit as its parameter but to increment as an unsigned and wrap 
to zero.

Is this a reliable interpretation in the general case, or if I use it to 
e.g. count how many times a thread "spins" are there other cases that I 
need to take into account?
