[VETO] fix aliasing warning

VETO But I mean that in the friendliest possible way. Ben Wing <ben(a)xemacs.org&gt; wrote: Sorry, Ben. I promised you I'd look into this quite awhile ago, but I never got back to you. Mea culpa. I just did and this patch is definitely incorrect. I am not surprised that it fools gcc into shutting up, but all this patch accomplishes is to make the compiler stop warning us about dangerous code. It doesn't actually remove the danger. I am going to continue being very busy through the weekend, and probably into Monday of next week, but I promise, cross my heart, I'll come up with a fix right after that. For the interested, the C99 Rationale explains the problem and what compilers are allowed and required to do. See http://www.open-std.org/jtc1/sc22/wg14/www/C99RationaleV5.10.pdf, specifically section 6.5, starting at the bottom of page 59, and section 6.7.3.1, page 77. -- Jerry James http://www.ittc.ku.edu/~james/
