[Bf-committers] Makefile support

[Campbell Barton]

After some days with no activity on this topic it seems the main
reason to keep nan-makefiles is because of Irix support.

This raises the question does Irix compile now with nan-makefiles?

Looking in the "lib/irix-6.5-mips" dir, referenced by
nan_definitions.mk, the last built python is version 2.2, (first
released 2001).

We also didn't release a 2.5x beta for Irix.

Supporting minority *nix OS's is fine but at some point I think we can
rely on their user communities to submit patches and making sure their
system is well supported.

I've used CMake on a few *nix OS's: netbsd, cygwin & linux.
In my experience the build-system only needs minor adjustments and
perhaps a few ifdef's in the code, by far the most work is in building
all dependencies blender relies on.


Could we treat Irix as we do NetBSD, OpenBSD, Solaris, AIX and similar.
accept patches and allow active users to support but not block changes
because of these systems?
