Zortech C used to have #message and #exit pragmas, which would cause a
message to be printed during compilation and the compiler to terminate

rejected the idea. The features were eventually removed due to complaints
about them not being ANSI C. No one complained about them being removed,
which I took to mean no one used them ...
