[problem with Turbo C 2.0 compiling 1.5.5 where a pointer would be cast
to a long and TC would put the segment in the upper part.]

Oops. My solution was to cast to an (int) before casting to a (long).
Bruce Evans has pointed out to me that casting to an (unsigned) would
be better because (long)(int) will sign extend while (long)(unsigned)
won't. I got away with (int) because I'm using separate I&D and so
all the pointers being converted were less than 0x8000.
