GNU C++ how to check when -std=c++0x is in effect?
What I want to do is:
#if defined(CPLUSPLUS_OXFLAG)
//do something
#else
//do something else
#endif
Now how can I capture -std=c++0x argument passed to the compiler(g++) to define my CPLUSPLUS_OXFLAG flag?
The GCC documentation states that the preprocessor symbol
__GXX_EXPERIMENTAL_CXX0X__is defined when compiling with-std=c++0x.
