but the former is of some random size..?


Wouldn't it be better to create a gg_int.h which ensures that uint32_t
etc is provided, either by including <stdint.h> if there is one,
or creating some itself ?

Or safer, perhaps, to have gg_uint32_t  which is typedefed to uint32_t
if there is one, or to unsigned int (with checks that int is indeed 32 bits)

Unfortunately, I'm not sure standard c lets you ask if a typename is known,
which makes it a little hard to test.  (eg there may not be a header called
stdint.h, yet including stdio.h might make these types appear anyway.
