UnixWare only has one sed. But there so many open source projects out
there that use GNU specific features os sed that it is common for
people doing development on UnixWare to install a GNU sed.

Looks good on my UnxiWare 7.1.4 box.
/usr/bin/posix/sh ./testsuite -k config.status -k AC_PROG_SED
## ------------------------------ ##
## GNU Autoconf 2.59c test suite. ##

Testing config.status.

 81: Torturing config.status                       ok

Testing autoconf/programs macros.

203: AC_PROG_SED                                   ok

All 2 tests were successful.

Not so good on my OpenServer 5.0.4 box
gmake[2]: Entering directory `/usr/local/src/gnu/autoconf-2.59c/tests'
/bin/ksh ./testsuite -k config.status -k AC_PROG_SED
/testsuite[900]: : is not an identifier
gmake[2]: *** [check-local] Error 1

BTW, This hunk failed on autoconf-2.59c as it was already 3.
