Normally, when I am working on a project that must be transportable, I
use a file on my system called "COMPILER_DEPENDENCIES.h" On a VAX, this
file looks like this:

#typedef int32 unsigned int
#typedef int16 unsigned short int
.
.
.

On my IBM/PC (lattice C, UGH!), the file is "COMP_DPD.h" and it looks
like this:

#typedef int32 unsigned long int
#typedef int16 unsigned int

I use sint16 for signed integers. Then, throughout the code, no int's,
just int16 or 32, depending on what. I want.

Hope this helps.
