That the expensive optimising C compiler was a ripoff.  :)

(However, if you're discussing SparcWorks C, you've failed to establish
that it's a C compiler.  A C compiler *MUST* diagnose the line
	static int i = 1 ? 1 : (++j);
as a constraint violation, but at least the version we have doesn't, even
in "maximally conforming ANSI mode".  Clearly, it is not a C compiler.)

Didn't you know?  It's an acronym for "Sun's Project Ada Revenge Chip", and
was designed to make things run 10 times faster in Ada than they would have
otherwise.  :)
