*sigh* I do wish people wouldn't review things without reading
them. I happen to agree with you about MAY NOT, but that's
what RFC 2119 says. The RFC is about 600 words long, BTW, and
here's a link: http://www.isi.edu/in-notes/rfc2119.txt .

*Everything*? So if a specification for a C compiler doesn't
*say* that compiling a strictly conforming program does *not*
make demons fly out of your nose, then the compiler is allowed
to do that?
