Pcc has a bug regarding constant expressions containing casts.  This was
recently brought up in net.lang.c regarding an expression to get a mask with
the high order bit on using

unsigned int mask=~(~((unsigned)0)>>1);

The VAX System III pcc will choke on this, and there were other versions
of pcc indited as well.
