Then, for Texinfo, we probably should set ac_executable_extensions in
djgpp/config.site, since I don't want to rely on the system-wide
config.site to set that (or even to exist) in a typical DJGPP
installation.

If Autoconf has a similar DJGPP-specific directory in its distro, it
could set ac_executable_extensions there and point CONFIG_SITE to that
file.

Thanks for explaining the other method (which should also be okay, I
think).
