That's odd... I never got that error. Right now, the quick fix for you would be
to remove the offending line:
_DEF_OBJECT_TYPE(String)

(I think it won't cause much side effet for you) while I try to find the
problem. What compiler are you using? I see the file to be
plugin_sensor_PL_main.c, is that C or C++? Also, could you send me the
pre-processed file so I can see what happened with the includes?

P.S. As a general rule when compiling Overflow: if it doesn't compile, remove it
and all the rest is likely to work. For instance, most of the times, you can
remove a .cc (when it's a node implementation) from the Makefile and everything
will keep working (just don't use that Node).
