No matching function error in Xcode 3

I am trying to compile a custom class in Xcode 3 and I keep getting a no matching function call error although the same custom class compiles fine under Windows. Obviously something is not right regarding the use of curly brackets and the XCode compiler. The compiler is choking at the first curly bracket { below:

  : ADataBrowser(inOwnerWindow,inID,inOwner), mEncoding(kTextEncodingMacRoman)
                    {
                        std::memset( mCustomLabels, 0, sizeof(CFStringRef) * kMaxLevelCount);
                    }

Any ideas much appreciated!

It looks like you're not including the file that declares std::memset.
