add -zu compiler flag to 16-bit real mode large and compact memory models. I think what's causing problems with the SNDSB test program in dos86l builds is that the SB IRQ interrupt function is calling subroutines and the subroutines are assuming that DS == SS when accessing parameters. -zu is how you tell Watcom C to not assume DS == SS when compiling.
