My news-system has been broken, first here then there, for a week or
more. It looks as though I may have missed some SLM's (silly little
macros) -- those infuriating little hacks that send you grepping around
in .h files. A while back, I decided to keep a file of the most disgusting
of the lot, all taken from actual practice. It has not grown very long,
because I have not been reading much code lately, having been in high
hack mode for months. The list follows. Should I add '#define OR ||'
and '#define AND &&'? In other words, is this from real code, or was
somebody just thinking out loud?

Notice that the most serious offender in the SLM category has a place of
dishonor at the very top. SLM's are presented with their original
comments.
