I would prefer if we went ahead and did your suggestion of doing check
with new macro on all systems instead of this.  I will be glad to test
on a sampling of Unix systems to make sure there are no issues.

So I'm saying I'd prefer this patch to change to delete old check for
get* functions and do macro unconditionally.

One thing I notice must be a bug.  Right before the old call to
AC_CHECK_FUNCS(), there is a check for BeOS and forces the variables
to be "no".  Those need to be after the AC_CHECK_FUNCS to be
meaningful.  I'm pretty sure BeOS support is broke in other ways.

Anyways, I'll probably submit a patch to fix BeOS bug along with your patches.
