Well quite !

Furthermore, if something is undefined by the specification then even if 
the actual (but undefined) behaviour is observed for a particular 
implementation (of the specifiation) and appears to be consistent 
betweeen invocations the very fact that it is undefined implies that you 
still cannot be confident that the undefined but observably consistent 
behavior will be consistent for the (infinite?) set of possible program 
states because it's undefined.

If you want to do stuff that lets you muggins about with the guts of the 
machine use c (and gdb) and be thankful to K and R

If you want to write portable code use Java

I have a sneaking suspicion that actually, c zealots are quite jealous 
of Java's ability to translocate with little trouble and try desperately 
to convince themselves that their favorite dialect is perfectly capable 
of producing portable code as long as you know the unknowable and 
studiously avoid using it ... the unknowable that is although how you 
know it when it's unknowable ... etc etc
