Unfortunately Cernlib was largely written in the 1970's and 80's long
before configure scripts came about... It uses Imake. Also, most of it is
in Fortran, and the authors apparently never considered the possibility
that sizeof(void *) might one day be bigger than sizeof(int) on some
machines; they do all kinds of horrible conversions between C pointers, C
ints, Fortran INTEGERs, REALs, etc.
Anyway, the reason I asked was that I want to know what I can change (e.g.
int -> long) to fix things on 64-bit without breaking library ABI
compatibility on 32-bit machines. (On 64-bit, breaking library
compatibility doesn't matter so much since most of the libs just segfault
right now.)
