Sounds like an idea.
Note that in sh one can also just define functions conditionally:
if $cond; then
func_foo ()
{
...
}
else
func_foo ...
also note that we have a section in libtool.m4 where we already define
some per-system functions which are then added literally to libtool.
That way, libtool doesn't ever contain the ones not intended for this
setup.
Cheers,
