* To avoid name collisions, we will rename macro variables by
* adding _prefix in front of the name of each variable.
* Returns the macro with converted names
* @param result If return value is false, this is not touched. If
* return value is true, this will contain new macro line
* (all that comes after #define) e.g.
* "A(__cppcheck__x) foo(__cppcheck__x);"
* @param macro The macro which is about to cause name collision.
* @return true if code needs to be changed, false is no changes
* are required.
