Yeah I have thought of that , now I got my windows box up and running 
again(well nearly , I cant install SP2 for some reason) , I'm going to give 
it a go

see this discussion

4) Get autotools to run NATIVE in windows with MSVC . What I have in mind is
really a trick , there are two parts to it , 1) get it use cl.exe instead of
gcc.exe 2) hide the fact that we are running under another shell.


autotools can run cl.exe , no problem , just like it can run cc or icc , the
options are a little different , but a script can easily take care of that 
(as
long as everything is one-to-one) , once we have this bit , then we could 
get
a MSVC compile under cygwin or minGW . The next stage is to have a "hidden
install" of minGW so we can run autotools, (just like we do for yasm under
linux).


Thanks
