A question just came up on IRC concerning the use of the /Za ("disable language extensions") and it not working. While searching for a previous post from STL on the subject [1] Google offered this link: <https://svn.boost.org/trac/boost/wiki/Guidelines/WarningsGuidelines> STL's (Stephan Lavavej's) advice on the subject was to *not* use /Za because it has "an extremely nasty bug". Unfortunately our guidelines suggest it should be used. I began to edit the wiki page but considering the amount of text and an example on the subject I thought it might be best to ask permission first. Should I edit the page to be in-line with STL's suggestion or just leave it as-is?
