I think most people prefer to use the cross-compile.
Stefan might do native compiles.

Since 2.7 the minimum version of glib has been 2.30 for Windows
(documented in http://wiki.qemu-project.org/ChangeLog/2.7),
because of this g_dir_make_tmp() dependency. Unfortunately
it looks like we forgot to update configure (we didn't for 2.7
because we noticed the issue quite late in the release cycle).
