[erlang-patches] Re: Fixes for building erlang under windows

[Dan Gudmundsson]

 From the README.win32
=>  Get and unpack wxWidgets-2.8.9 or higher to /opt/local/pgm inside cygwin
                                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The configure script only looks there on windows when building with VC++
We didn't try anything fancy for the windows build there are so few building
from the source on that platform.
