[zeromq-dev] portable uint32_t ?

in my code, i define these sorts of things in a basic.h
and also write a basic_check.c
which verifies if (using code like if(sizeof(uint32) != 4) barf();).
and this is run as part of installation.

it is only a short step to putting that into a configure like program.

you can also try being clever with MAX_INT (or whatever it is called)
#define short uint32
#if MAX_INT > 0x7FFF
#define int uint32
#define long uint32

but i woudl check as well.
