Yes.  There are still 1.5.x users out there, but my patience with them
is starting to go down.

Yes, if it has been tested that it will skip when Libtool 1.5.x macros
are in place.  LT_PREREQ has been introduced in 1.9b only.  Also, I
think that if the LT_PREREQ check fails, it will fail already at aclocal
run time, but I am not sure of that.

Thanks,
Ralf
