Damn, I always assumed that min/max are macros and took into account #2,
which was painful sometimes. :-)

The fact that it is defined in sock.h (and the definition is truly
crazy, add #4: it is funny what happens on 64bit archs, when one of args
happens to be long)

min/max are macros. I do not know how to make a valid inline
for it: cast to long has problems with unsigned longs, cast to unsigned long
have the same problems with signedness.
