Hi Isuru,

Thanks for your mail.

min+max:  I think that's a C standard violation but we will avoid it by 
renaming our functions

AR:  good idea, I'll do it

sizeof(long): yes, it is a bug.  I need to store a long or a pointer in 
the same place.  I'll work on this soon, probably using a union type.
