compiling C++ is and probably always will be a lot slower than compiling
C - there is just a lot more work for the compiler to do. it gets
particularly bad when there is heavy use of templates, as is true in
sigc++ and gtkmm.

with gtkmm in particular, one trick is to avoid including
<gtkmm/gtkmm.h> in your source files. instead, include
<gtkmm/SomeWidget.h> for all the widgets and classes used in that file.
the effect will not be huge - things will still be slow - but it does
help a little.
