I just downloaded it again to check the md5, and it matches...

Then might I suggest you stop shipping broken makefiles?  It would have 
helped me not waste a day.

I found the nutconfigure tool, and managed to get everything set up (I 
think -- am yet to see if this build actually runs).

Given the stunning lack of documentation, it's hard to know what's me 
not knowing what to do, and what's "deprecated" things... I guess I 
should add a page to the Wiki on "The complete newbies guide to avoiding 
all the leftover kruft in NutOS"...

Looking closer at the code, what you say is becoming obvious.  It also 
conspicuously lacks a "NutMsgQEmpty" or similar function...

Well, once we get this project done, I might have a refreshed NutQ 
alternative to contribute.

Wouldn't mind hearing from others if
a) anyone is using it
b) anyone would use it if it had feature X
