87 | /* XXX A note on the perl source internal type system. The |
88 | original intent was that I32 be *exactly* 32 bits. |
89 | |
90 | Currently, we only guarantee that I32 is *at least* 32 bits. |
91 | Specifically, if int is 64 bits, then so is I32. (This is the case |
92 | for the Cray.) This has the advantage of meshing nicely with |
93 | standard library calls (where we pass an I32 and the library is |
94 | expecting an int), but the disadvantage that an I32 is not 32 bits. |

97 | There is no guarantee that there is *any* integral type with |
98 | exactly 32 bits. It is perfectly legal for a system to have |
99 | sizeof(short) == sizeof(int) == sizeof(long) == 8. |
693762b4 |
100 | |
dc45a647 |
101 | Similarly, there is no guarantee that I16 and U16 have exactly 16 |
102 | bits. |
693762b4 |
103 | |
8e84507e |
104 | For dealing with issues that may arise from various 32/64-bit |
105 | systems, we will ask Configure to check out |
