Large projects, and even some small ones, are generally
compiled using make.  Makefiles can execute _whatever_ is desired
for user messages, even X clients.

AFAIK, make generally aborts processing unless told, with an
option switch, to do otherwise.  To force a bail-out from
compiling or pre-processing, one _could_ intentionally
introduce errors.
