Simple. I don't want to go back to the old ways of

#ifdef MIT
#elif HEIMDAL
#elif..
#endif

way of doing code. That way ends up as 

#ifdef HPUX
#ifdef HPUX_4_2
#endif
#elif SOLARIS_5
#elif SOLARIS_7
...

horrors that took many years to escape from.

Heimdal and MIT are a *mess*, in terms of adopting
standard API's and methods. Nearly as bad as we are
with Samba3/Samba3 (just in case anyone thinks I'm
being too hard on them :-) :-).

As far as possible, let's detect features not version
numbers please. That way lies madness.

Jeremy.
