This thing is because you dont have GTKMM_HAVE_MUTABLE defined. It should
be there if your compiler supports mutable... Newer gtk-- versions include
automatically gtk--config.h that has the define properly set - with older
gtk-- you need to do that manually.

However, if your compiler doesnt support mutable, then you have to
watch ugly warnings :) (gcc2.7.2 I think gives the warning...)
