I wonder how much of the perceived difficulty of Windows as build platform
is really the fault of Visual Studio. I find it quite easy to install.
But the required Cygwin install could be better documented: I have a text
file somewhere with all required packets, but I do not know if an official
Then there is the annoying freetype dependency, which soon will be history
thanks to Phil Race (8193017).
Also, installing Visual Studio could be easier by making sure that we
always can build with the latest community version, early when it comes
out. Since it is not so easy to find community/express/whatever downloads
for earlier versions of Visual Studio.
(Just my 5c).
Best Regards, Thomas
