Heh.

I have occassionally been bitten by mawk/gawk differences.  One ISTR
had to do with whether

        /[\]/

had instead to be 

        /[\\]/

I once complained to the NetBSD developers that the base system seemed
to have a few different regex implementations.  I was then informed the
actual count was, at the time, 17.  I suppose that's an example of
competing with your own release.
