4 uberlord 2868 # We should strive to keep this Makefile working with the default make
5     # shipped with the OS's we support. Mainly because I'm lazy and just want
6     # to type make instead of gmake, but also so that other distros can pick
7     # it up and not rely on GNU Make.
8    
9     # NOTE:- FreeBSD and DragonFly have no way of optionally including files
10     # that works with GNU make and vice versa. NetBSD and OpenBSD makes do.
11     # You can get a patch from
12     # http://www.freebsd.org/cgi/query-pr.cgi?pr=standards/116081
13     # to fix this. We include this patch with Gentoo/FreeBSD :)
