I'm trying to compile ghostscript 2.5.2 on a cray under unicos.  The
first problem is that ints are 8 bytes, which causes a problem in
gdevmem.h at:

/*
 * The clog2_bytes macro assumes that ints are 2 or 4 bytes in size:
 * check this now.
 */
#if !(arch_sizeof_int == 2 || arch_sizeof_int == 4)
#  error sizeof(int) must be 2 or 4 for correct operation.
#endif
/* Generic macros for chunk accessing. */
#define cbytes(ct) ((int)sizeof(ct))    /* sizeof may be unsigned */
#  define chunk_bytes cbytes(chunk)
#define clog2_bytes(ct) ((int)sizeof(ct)>>1)    /* works for 1,2,4! */

My questions are:

1) Is this a hopeless task?  Has anyone succeeded or tried and failed
   at this?
b) Is there a work around for this macro, or does this particular
   assumption  about the length of ints appear elsewhere?

Thanks,
