	Premake4 can generate gmake files if desired.  But, I'm not going to
suggest that due to the complexities of various linux builds which you've
already dealt with in the makefiles/autoconf.  Premake is great for Os X and
Windows though, you generate the solutions/xcode projects for whatever you
want, 32/64 bit, debug/release, whatever options you want.  As to the file
list, I just hand coded that myself, it was quick and easy and got 0mq to
work in our build pipeline at work and my personal pipeline at home.

	As a note, I've used 0mq in 64 bit compiles several times and not
had any issues.  My build scripts already generate solutions with 32 bit and
64 bit targets.

	Premake is not dependent on Lua, it "is" lua, just with extensions.
The source to premake or the binaries are completely standalone with lua
included directly and not as an external item to go get/build.

	Agreed, I could probably figure out a method to extract the file
information directly from the make file.  Premake being lua means you have
the full language available to write whatever you want, you don't "just"
have to generate make files with it.

	This would just be a "go to xyz website and get the binary" for the
most part and of course for Window's users only.  VS2k10 support is in the
release candidate though so you have to point to the latest version.  I'd
actually be surprised if most Window's dev folks don't already have
Premake/CMake installed since so many projects have already started
switching to them for Windows support specifically.

	Given the push for alpha around here, I'm pretty much unavailable
except for a couple hours here and there.  But, this is fairly simple and
small, "maybe" I could whip up a quick example this weekend.  No promises
