compiling Maxima for Windows



So, as Maxima for Windows approaches a year since its last 'refresh', 
was wondering if there is a canonical reference as to the steps for 
'rolling our own' (i.e., compiling not only Maxima, but the installer). 
Beyond the ignominy of actually being 'behind the Mac version'  ;-), 
there are some practical needs for a refresh.

The fact that it hasn't been done in ~10 months suggests the compilation 
is non-trivial (what my shop calls 'brittle' - stand on left foot, close 
eyes, face north, and type 'make', and hope it works), but I suspect 
there are several folks out there (or is it here) who would be willing 
to give it a shot.
