standard library calls (where we pass an I32 and the library is
expecting an int), but the disadvantage that an I32 is not 32 bits.
Andy Dougherty August 1996
+
+ In the future, we may perhaps want to think about something like
+ #if INTSIZE == 4
+ typedef I32 int;
+ #else
+ # if LONGSIZE == 4
+ typedef I32 long;
+ # else
+ # if SHORTSIZE == 4
+ typedef I32 short;
+ # else
+ typedef I32 int;
+ # endif
+ # endif
+ #endif
+
+ except that still won't work if a system has no integral type
+ with a size that is 32 bytes.
+
+ Further, we need to know about PTRSIZE == sizeof(void *) and
+ DOUBLESIZE == sizeof(double) if we really want to try to handle
+ 32/64-bit combinations.
+
+ For the moment, these are only mentioned here so metaconfig will
+ construct Configure to figure out the various sizes.
