The patch to .SET pushed TT onto FXP around a PUSHJ P,BIND ...however,
if BIND gets PURPG interrupt stuff for the SFX'ed frob at SETXIT gets
pushed onto FXP, so what gets popped is not what got pushed, and what
is left is not what what SPWIN was looking for. So I changed the patch
on MC to save TT onto FLP instead of FXP. This fixes the (SETQ T NIL)
getting a PURPG error. However, I note that there is no trace of this
patch in the source at all!
