* Add new type SUINT32, as a shorter version of UINT32 for systems that
do not have a proper uint32_t type. SUINT32 is defined by default to
be UINT32, but during compilation the user can define an environment
variable SUINT32 to be, say, unsigned long, and that will make SUINT32
to take that type. This, and the source codem, are the only places
where this is documented. Work in collaboration with professor Martin
Trusler.
