Installer for Windows, was: Maxima 5.30.0 / wxMaxima 13.04.1 Windows Binaries

I tried the new installer.  Thanks, us Windows addicts have not had a new 
version in a while.  I have not tested it out that much yet but I did notice 
that load(draw) does not work.  Consequently I can't get draw, draw2d, 
draw3d, etc to work.

Here is the error.

These are known issues with gcl.  While the error is small, it should
be zero.  I think the issue is that gcl is not correctly rounding.
