My notes and memory are both somewhat fuzzy on it.
I think that the GLIB_VERSION_MIN/MAX macros only went in in 2.32
but then once you have them they offer a range allowing you to state you
need a minimum of 2.26; so if we bump the minimum to 2.26
then becareful to check it still works at that.
The interaction of stuff that includes glib.h and others that
include glib-compat.h was messy; I was working on the assumption
that stuff that included glib-compat.h knew it was using newer
things and didn't expect a warning; the problem that Peter
pointed out was that glib-compat gets included by qemu-common so
actually the warnings get disabled in loads of places.
