It fixes the warning regarding redefinition, but the build fails nonetheless.

Actually it's very strange:
Have a look at function_run (line 3772): the build fails, if there is anything (except white space) between the { after the if (#3785) and BUILTIN_FUNCTION. As the macro expands to nothing, only the semicolon remains and the build fails. Replacing the macro with a singular semicolon has the same effect ([1] for preprocessor results). 

I have no idea what's the actual cause for this... 

Regards, 
Stefan
