Finding the most recent and official Windows build of gtk+ or gtkmm requires a futile herculean effort.

This website is outdated and the Windows link is dead http://www.gtkmm.org/en/download.shtml
This is all very outdated ftp://ftp.gtk.org/pub/gtk/2.24/
This from 2010 http://ftp.gnome.org/pub/gnome/binaries/win64/gtk+/2.22/
And according to http://www.gtk.org the latest stable version for Linux is 3.8 which is also false as it is actually 3.10.7, so the text on the Windows page stating "GTK+ 2.22 is the current maintained version" must also be assumed to be false.                                                                                                                                                                                                                                  
There's a 2.24.2 here http://sourceforge.net/projects/gtk-mingw/files/gtkmm2/ but one of our Windows builders says its missing packages (waiting for more detailed info).
The latest GTK+ builds on http://sourceforge.net/projects/gtk-mingw/files/gtk%2B2/ are 2.24.11 which are a year and a half old. Current gtk+ is 2.24.22 but I can't find any Windows builds.

I understand that GTK+ and gtkmm are different projects, but as websites that host builds of one often host builds of the other, and as I assume there is some level of communication between the two projects, I hope this report reaches both teams. Generating stable builds of our program which uses GTK+ 2 is becoming more and more difficult due to the disparity between actual GTK+ versions for Linux vs outdated ones for Windows, and rewriting it in GTK3 would require likely over a year of coding to get it to the same level for which we just don't have the manpower. In light of the mess in getting GTK+ builds which are recent for all platforms, we have increasing motivation to move away from using GTK altogether, should the manpower to rewrite the program be found. The current situation is... depressing.
