Got me as to why it does that.  That change was checked in by Zastai on
2001-09-20.  Here's the ChangeLog entry:

        2001-09-20  Tim Van Holder  <address@hidden>

                * lib/autoconf/programs.m4: Use extensions listed in
                $ac_executable_extensions when looking for programs.

Perhaps Tim can comment.

It might make things easier for you if you set SHELL=sh in your
environment before futzing with this stuff.  No sense tilting
at windmills....

I don't see this in CVS Autoconf.

Ugly, but not fatal; it just doesn't use -g.  You can set
CFLAGS='-Zomfg' if you want -g.

Sounds like you have an old Autoconf; I think that bug was fixed in
<http://mail.gnu.org/archive/html/bug-fileutils/2001-09/msg00037.html>.
Anyway, that's from AC_ISC_POSIX. I'd just stop using that macro; it's
obsolescent.
