Please try with ac_cv_sh_n_works=no set and exported in the environment
before building and testing autoconf. I think ksh93 should be removed
from the list of shells with working sh -n.
Can we boil things down to a simple test case of the use of ksh -n that
causes all these test failures? If so, then the real fix would be to
fix the .m4 file that sets ac_cv_sh_n_works in the first place.
I'd like confirmation from Martin that this is the issue first :-)
If it is then the patch is trivial:
--- a/configure.ac
