Trying to use jsoncpp 1.6.2 on Cygwin, using g++ 4.9.2 with C++ 11 features enabled; compilation fails on:
/jsoncpp-1.6.2/dist/jsoncpp.cpp:3969:18: error: ‘snprintf’ is not a member of ‘std’

Switching to non-C++ 11 jsoncpp branch, 0.10.2, yields a similar error:
/jsoncpp-0.10.2/dist/jsoncpp.cpp:3790:18: error: ‘snprintf’ is not a member of ‘std’

Turns out Cygwin has a bug where std::snprintf is not included when using C++ 11 features.

Checking amalgamated jsoncpp.cpp, turns out it still has C++ 11 detection, which it shouldn't have:
line 3787:

if defined(_MSC_VER) && _MSC_VER < 1500 // VC++ 8.0 and below

define snprintf _snprintf

elif __cplusplus >= 201103L

define snprintf std::snprintf

endif

What applies in this case besides removing the std:: from that define?
