43 this file first, then you will have to manually set -DHAS_BOOL in

75 /* XXX A note on the perl source internal type system. The
76 original intent was that I32 be *exactly* 32 bits.
78 Currently, we only guarantee that I32 is *at least* 32 bits.
79 Specifically, if int is 64 bits, then so is I32. (This is the case
80 for the Cray.) This has the advantage of meshing nicely with
81 standard library calls (where we pass an I32 and the library is
82 expecting an int), but the disadvantage that an I32 is not 32 bits.
