I may be totally off base here, but:
INT32's comment suggests that the configure script checks that int is >=
32 bits. However, i don't think that script's around anymore, and ANSI
specifies a minimum of only 16 bits.
The comment also says that INT32 can be 64 bits, but it's then used as
Tflag, whose comment says it can't be > 32 bits.
Maybe we should just replace it with int32_t?
I also fixed a couple adjacent comment typos.
