This is absolutely the correct list.

Thanks very much for putting in the effort to do this.

This may be a problem.

The material on the Xming website is licensed under a Creative Commons 
license, which is not compatible with the X11 license.  So, patches from the 
Xming website are not acceptable unless the author has agreed to re-license 
them appropriately.

I've quickly looked over these patches and in general they look good, and I'd 
be happy to help get them merged upstream.

A couple of general points I'd make though:

It helps a great deal in reviewing if the comments state why the change is a 
good idea (e.g. what problem it fixes), rather than just describing the change 
which is made.

I also noticed that a bit more care might be needed with the define you are 
using to enable platform specific code: WIN32 and __MINGW__ should not be used 
interchangeably.  WIN32 will also be defined when building VcXsrv, and neither 
is defined on Cygwin.

So, can you post your patches here, preferably in git-send-email format so we 
can review them in detail?
