I would like to know of C compilers for OS/2 and their relative
merits/demerits. I have the following gripes with MS C5.10
that I currently use:

1. Can't generate native 386 code.\

2. Pointer arithmetic is 16 bits wide. I use a lot of *large*
   data-structures (created with DosAllocHuge ()), and pointer
   arithmetic bombs at segment boundaries. It's plain painful
   to use a cast thus:

ULONG HUGE *x, HUGE *y;
ULONG PDiff; /* a difference > 16K means another segment ... */

x = (ULONG HUGE *)(y + PDiff);
or worse still, transform x++ to
x = (ULONG HUGE *) (x + 0x1L)

   Downright ridiculous. Are there any compilers (I use OS/21.1 BTW)
   that don't have these problems?

Thanks
