Equality vs Assignment

[Chris Gray]

The proper place for this check is of course as a warning issued by the C
compiler. It's not all that hard - it took me about 30 lines of code in the
compiler (ANSI draft based) that I've done. It's a check I felt was quite
important, since I've been bitten by it too many times (I program in other
languages besides C, where '=' IS a comparison).
