Whoops, I forgot to replace it!  After replacing tstbit.c and running
configure with --target=none-hp-hpux10.20 CFLAGS="-g -DNO_ASM -O2"
everything compiles AND checks out fine.

However, when letting configure go on its default settings, the compilation
goes fine but the tests fail as shown below.
