When I compiled GDAL I used external libraries as much as possible, to 
keep the binary size down - but that was the only reason. For 
compatibility probably better to use the internal ones.

I agree with that - it was quick and easy to get working before I realised 
how easy it was to compile Tcl/Tk on Windows anyway.

That would be good.

On the WinGRASS wiki page there is a link to a binary package that I 
provided containing:
xdr-4.0-mingw32
proj-4.6.0
gdal-1.5.0
fftw-2.1.5
tcl-8.5.0
tk-8.5.0

However those versions are 5-6 months old so it would be great to get 
things up-to-date. And ultimately I can see us providing simple binary 
packages on the GRASS site, while people looking for a point & click 
installer could be directed towards OSGeo4W. I think that would keep 
server disk space requirements in check, among other things.
