nw-gyp auto add _HAS_ITERATOR_DEBUGGING=0 to compiler defines for debug

[WJsjtu]

nw-gyp auto add _HAS_ITERATOR_DEBUGGING=0 to compiler defines.

This prevents me from linking many external static libs with such error.

Is this macro really needed? This is really hard for me. I may add _HAS_ITERATOR_DEBUGGING=0 to my own lib but for external libs or lib depends on external libs I cannot do anything but compiling them fron source.

I've also tried node-gyp and found no such problem.
