This might not be a "pure" Boost question but do you know if compilers portably support the 'not' keyword?
int main ( ) { if(not false) return 0; return 1; }
This compiles on GCC but not on MSVC... Why? If you look at the C++ standard, it says that 'not' is part of the language...
I'm not sure why you didn't ask this question on comp.std.c++ instead, but... MSVC requires you #include <ciso646> to get the keyword alternatives, although I've no idea why (since I've recently started to like them). IIRC, you can also pass /Za to the compiler to disable MS extensions, which will then re-enable these keywords. Again, don't ask me. One thing I'm a little curious about is whether the keywords are allowed in Boost libraries. Cheers, Darren
