int/ptr size mismatch warnings with gcc 3.2 on Linux on ia64

[Jeff Trawick <tr...@attglobal.net>]

use mod_cgid from HEAD an example...

mod_cgid.c: In function `cgid_server':

AFAICT, all these operations are safe on systems where sizeof(int) <= 
sizeof(void *) and sizeof(pid_t) <= sizeof(void *) (i.e., just about 
everything where you'd expect to run Apache or APR).  Is anybody seeing 
stuff like this with other compilers?

The attached clumsy patch below axes the warnings, but it sure seems 
like overkill.  Allocating extra storage from pools to get rid of the 
warnings doesn't seem to be cool either.
