From: Matt Kraai <redacted> QNX 6.3.2 uses GCC 2.95.3 by default, and GCC 2.95.3 doesn't remove the comma if the error macro's variable argument is left out. Instead of testing for a sufficiently recent version of GCC, make __VA_ARGS__ match all of the arguments. Since this should work on any C99-compliant compiler, also remove the tests around the macro definition.
