OK - I'm seeing similar results now (even with more complex examples - 
about 4 times faster). I guess my problem was that the precompiled 
header should be named gtkmm.h.gch and not gtkmm.gch. However, I quickly 
stumbled across GCC bug 13675 
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13675), which was rather 
easily worked around by using 2 include files like:

A.h:
#ifndef A_INCLUDED
#define A_INCLUDED
#include "B.h"
#endif

B.h:
#include <gtkmm.h>

and then precompiling B.h, while including A.h in my source files. So it 
seems that it's not quite ready for prime time yet, but I still think 
it'd be rather interesting to have a build target for gtkmm.h.pch in the 
standard gtkmm makefile.
