Well on the AT90CAN128 with no external RAM, code memory is ample and RAM is
few. Adding a printf_P with the version string brought down available heap,
so I was thinking about how to keep that usefill feature witout scrificing
RAM...
But thinking again, probably most usefull would be to have 
#define OS_VERSION_NUMBER  0x04090700UL
in sys/version.h an so one could construct PROGMEM strings with it and use
it for conditional compilations.
Sorry for wasting your time. 

Bye
