Actually the usually preferred way to do #error is thus:

#if SOME_PROBLEMATIC_CONDITION
 #error Fix me.
#endif

This works because K&R preprocessors don't recognise preprocessor
directives unless the # is in column 1.  In this case, they would pass
the "#error Fix me." text through to the compiler, which will barf just
as it would without the "#error".  The advantages of this technique are
(1) ANSI compilers will abort properly, and (2) it makes it clearer
that this is intended to abort compilation.
