How is that supposed to work? $ gcc -xc++ -std=c++98 -dM -E - < /dev/null | grep cplus #define __cplusplus 1 $ gcc -xc++ -std=c++0x -dM -E - < /dev/null | grep cplus #define __cplusplus 1 Actually I'm wondering if that's not a bug in gcc: $ gcc -xc -std=c89 -dM -E - < /dev/null | grep STDC #define __STDC_HOSTED__ 1 #define __STDC__ 1 $ gcc -xc -std=c99 -dM -E - < /dev/null | grep STDC #define __STDC_HOSTED__ 1 #define __STDC_VERSION__ 199901L #define __GNUC_STDC_INLINE__ 1 #define __STDC__ 1 [~]$ gcc -xc++ -std=c++98 -dM -E - < /dev/null | grep STDC #define __STDC_HOSTED__ 1 #define __STDC__ 1 [~]$ gcc -xc++ -std=c++0x -dM -E - < /dev/null | grep STDC #define __STDC_HOSTED__ 1 #define __STDC__ 1 Shouldn't -std=c++0x include the definitions for -std=c99, namely #define __STDC_VERSION__ 199901L ???
