And there are more references to be found using google.

a few common ones
I16L32P16 or IP16 ("small/tiny" model)
I16LP32 or LP32 ("large" model)
ILP32 ("flat" model, DJGPP, Win32, most common now)
I32LP64 or LP64 (64-bit *nix)
IL32P64 or LLP64 or P64 (Win64)

The last one is a little funny since a pointer does not fit in a
long any more, i.e.,
char *b = &foo; unsigned long a = (unsigned long)b; truncates.
and size_t is a "long long" or "__int64".
