Use autoconf; in configure.in, run a test program which uses the CTree,
set a variable in config.h depending on whether it works.
 
A simpler thing to use is:
extern const guint gtk_major_version;
extern const guint gtk_minor_version;
extern const guint gtk_micro_version;

(from gtkmain.h)

But it's more error-prone that autoconf because you have to keep track of
which versions work.
