For DirectX, I think it should be very similar:

DXDIR=/usr/local/dx7sdk
override CFLAGS += -g -O -ansi -I../pa_common -I$DXDIR/include^M
override LIBS += -L$DXDIR/lib -ldsound -lole32^M
PASRC = ../pa_common/pa_lib.c pa_win_ds.c dsound_wrapper.c^M
PAINC = ../pa_common/portaudio.h^M
PAOBJ = ../pa_common/pa_lib.o pa_win_ds.o dsound_wrapper.o^M
^M

There's no pa_asio dir included, but ASIO should be something like:
ASIODIR=/usr/local/asiosdk2
override CFLAGS += -g -O -ansi -I../pa_common -I$ASIODIR/host/pc \
      -I$ASIODIR/common -I$ASIODIR/host^M
override LIBS += -L$DXDIR/lib -lstdc++ -lole32 -luuid^M
PASRC = ../pa_common/pa_lib.c iasiothiscallresolver.cpp 
$ASIODIR/common/asio.cpp \
      $ASIODIR/host/asiodrivers.cpp $ASIODIR/host/asiodrivers.cpp \
      $ASIODIR/host/pc/asiolist.cpp^M
PAINC = ../pa_common/portaudio.h^M
PAOBJ = ../pa_common/pa_lib.o iasiothiscallresolver.o 
$ASIODIR/common/asio.o \
      $ASIODIR/host/asiodrivers.o $ASIODIR/host/pc/asiolist.o
^M

 For portmixer, I imagine it will work similarly, but there's not
a px_win_ds or px_asio directory.
