ICU now uses namespaces. When trying to use the scrptrun.h header, the header cannot compile stand-alone as it is inheriting from UObject which is namespaced now. Add namespace macros to properly inherit. ICU-20566 Add scrptrun to the extra high level Makefile The scrptrun project was not being added to the extra portion of the ICU build. Add it as a sub project so it can always be built. ICU-20566 Properly namespace the ScriptRun test The ScriptRun class is now namespaced. Update the test reference. ICU-20566 Use int instead of void to compile Clang will complain about having a void main without an int main to invoke. Change void to int and return 0.
