How about going even one step further and use 4 full hex digits.
Inspired by Python[1] and the Linux kernel[2] I propose to define:

#define KDE_VERSION_MAJOR 3
#define KDE_VERSION_MINOR 2
#define KDE_VERSION_MICRO 0
#define KDE_RELEASE_LEVEL b2

#define KDE_VERSION_STRING "3.2.0 beta2"

#define KDE_VERSION_HEX ((KDE_VERSION_MAJOR << 24) | \
                        (KDE_VERSION_MINOR << 16) | \
                        (KDE_VERSION_MICRO <<  8) | \
                        (KDE_RELEASE_LEVEL <<  0))

Together with

#define KDE_CALC_VERSION(a,b,c) (((a) << 24) + ((b) << 16) + ((c) << 8)

one could even avoid direct usage of the raw hex number by using

#if KDE_VERSION_HEX < KDE_CALC_VERSION(3, 3, 1)
 ...
#endif
