That depends on what the discrepancy is.  Many generated files
(compiled, or typeset documentation) contain some timestamp, or the name
of the host on which they were built.  Of course this will change
between two builds, and is perfectly normal.

It is still annoying, however, if you want to check if a particular
change in some package breaks the building of other ones - if they don't
FTBFS, you have to be very careful to spot the actual differences
without getting many false positives.  I'm currently undertaking a
similar effort; but have not gotten much beyond the manual state.  What
little automation I have is at 


What do you do to look at the differences?
