Undefined search term
I vaguely remembered a Raymond Chen post on some sort of undefined behavior that I wanted to check out, so I searched his blog for the word "undefined". Turns out blogs.msdn's synonym database and/or bolding is... a little odd:
C language is basically a bunch of undefined behaviors with a little bit of standard library built upon it. And WIN32_LEAN_AND_MEAN is initially undefined.
Turns out Bing's synonym database and/or bolding is... a little odd
FTFY, because the MSDN blog search is powered by Bing, and you get similar oddities searching on Bing itself.
