# We should strive to keep this Makefile working with the default make
# shipped with the OS's we support. Mainly because I'm lazy and just want
# to type make instead of gmake, but also so that other distros can pick
# it up and not rely on GNU Make.
# NOTE:- FreeBSD and DragonFly have no way of optionally including files
# that works with GNU make and vice versa. NetBSD and OpenBSD makes do.
# You can get a patch from
# http://www.freebsd.org/cgi/query-pr.cgi?pr=standards/116081
# to fix this. We include this patch with Gentoo/FreeBSD :)
