C++ file triggering the same error.

While trying to port libsigrok to NetBSD, I stumbled across the following compile error in bindings/cxx/classes.cpp:

*** [bindings/cxx/classes.lo] Error code 1

I have narrowed this down to a small test file, attached below. This file compiles just fine using Ubuntu 14.10 (gcc 4.8.4, glibmm 2.39.93-0ubuntu1), but not using NetBSD 7.0 (gcc 4.8.4, glibmm 2.44.0).

There is a workaround: After removing the two #defines, the test code compiles cleanly on NetBSD.
