Something that has to be done to break a network program
(typically a mailer) on a non-
Unix system so that it will
interoperate with Unix systems. The hack may qualify as "Unix
brain damage" if the program conforms to published
standards
and the
Unix program in question does not. Unix brain
damage happens because it is much easier for other (minority)
systems to change their ways to match non-conforming behaviour
than it is to change all the hundreds of thousands of Unix
systems out there.
An example of Unix brain damage is a
kluge in a mail server
to recognise bare line feed (the Unix newline) as an
equivalent form to the Internet standard newline, which is a
carriage return followed by a line feed. Such things can make
even a hardened
jock weep.
