Did some more testing, and as a matter of fact it is quite possible.
Running:
  g++34 -c `pkg-config --cflags gtkmm-2.4` -o gtkmm.gch 
/.../include/gtkmm-2.4/gtkmm.h

indeed produces a whopping 40MB .gch file. Unfortunately, it does 
nothing good for compile times... Testing it with the helloworld example 
added ~5s on the compile time, and for the slightly more complex 
cellrenderercustom/testpopup example, which also uses <gtkmm.h> 
throughout, the compile time is about the same as without a precompiled 
gtkmm.h.

I don't know if I did something wrong, or if that's how it works. But 
OTOH the gtkmm headers are very different from the stdc++ headers in 
that they are almost 100% declarations, so a different result is not 
surprising.
