Dev talk:Mingw installation

Without cairomm installed from the gtkmm package, I saw this error:

 $ pkg-config --cflags gtkmm-2.4
 Package cairomm-1.0 was not found in the pkg-config search path.
 Perhaps you should add the directory containing `cairomm-1.0.pc'
 to the PKG_CONFIG_PATH environment variable
 Package 'cairomm-1.0', required by 'gdkmm', not found

so I added cairomm to the list of elements from gtkmm which are needed.

GTK and git stuff

Ok gtk should be downloaded from the direct gtk.org website not the work around pages listed. Git can be accessed and gotten with tortoise and it's required components for the git version to work. Other than that i've almost got it updated.
