OK, I'll try again to make hstrerror work.

I used nsr because that's what showed up when I looked at *features*. I
guess the "nonstop" in the aclocal.m4 didn't take effect for some reason
and the "nsr" derived from uname was used. My other aclocal.m4 changes
did apply after autoconf, so I'll look into it.

Actually, I first tried to port ecl about a year ago and got as far as
the GC. Boehm did incorporate my changes with version 6.8, and they are
in your gc source as well. Unfortunately, I discovered a bug recently,
so the following still needs to be changed:

Thanks for incorporating the changes. I'll let you know how the testing
goes.
