I know all this. So a pthread_t is 32 bits in most cases and
64 bits on Windows. So what ? It just shouldn't matter as long
as you don't transfer binary data containing a pthread_t from
one platform to the other. 

Just **don't cast it** and use pthread_t wherever the data is
in fact a pthread_t. It will compile and work on all platforms
that have pthread_t. That it is a 64-bit struct in some cases 
shouldn't matter, C functions accept a struct as a parameter
and can also return a struct.

BTW, on Linux pthread_t is not a pointer. It's a long int.
Not that it should matter.
