Due to a bug in the libc headers, adding the "-std=c++0x" flag may break your project without legit reason.
If you encounter issues with undefined math functions, you may try to use -std=gnu++0x instead or to add "-U__STRICT_ANSI__" after -std=c++0x to the c flags.

AFAIK, the dialect option in the build settings is only for C, not for C++
