More accurately, names begining with /two/ underscores, or an underscore 
followed by a capital are reserved for the vendor by the standard, ie:
__special_vendor_name,
_Special_vendor_name2.
Just an underscore is generally fine, especially uglifing variables for 
class initialisation:

        class X {
                int y;
        public:
                X(int _y) : y(_y) {}
        };
