I have a class to wrap string literals and calculate the size at compile time. The constructor looks like this:
Prior to C++11, and as a standard programming idiom, temporaries are often assigned to variables to make the code cleaner. For small types a copy is typically made, and for larger types perhaps a refe

In C++0x, I would like to determine if a class is trivial/has standard layout so I can use memcpy(), memset(), etc...
What is the difference between Apple gcc and GNU gcc? Is Apple gcc a superset of the standard one? The g++ version information in my OSX shows:
