Re: [boost] MSVC doesn't support "not"?!

For reasons lost in history, it is considered an MS extension NOT to recognize these symbols. If you select "Disable language extensions" it will work (but not much else, like compiling Windows.h).

Note that /Za will cause <atomic> to explode due to inline x86 assembler using "and", etc. (which I am very eager to eradicate as soon as I can get more intrinsics from the compiler back-end). However, <atomic> defends itself from iso646.h's macros. /Za used to incorrectly reject vector although that seems to have been fixed. STL
