[Dev-C++] Compiler options : g++ vs gcc

[er <erw...@gm...>]

Hello,

When I compile a program (Win32 console) I get a lot of

[ Link error ] unreferenced std::string:: ....

which an error which based on posts I saw elsewhere (stackoverflow etc.) 
can be solved by compiling with g++ rather than gcc.

Where in the dev-c++ IDE and how do I specify g++?

I know it's possible because I have another project that shows g++ exe 
in the compile log rather than gcc.

Thanks.
