It's most easy to use cc instead of wpp. Below you see the cc and wpp command line:
# cc hello.cpp -o hello
/usr/watcom/10.6/bin/wpp386 -zq -ms -4r -i=/usr/watcom/10.6/usr/include -i=/usr/
include hello.cpp
/usr/watcom/10.6/bin/wlink op quiet form qnx flat na hello op priv=3 op c libp /
usr/watcom/10.6/usr/lib:/usr/lib:. f /home/root/cpp/hello.o op offset=40k op st=
32k
