title: Eclipse CDT: error: '::wcstold' has not been declared using MinGW
body: <p>I'm trying to compile my game, originally written in VC++, in Eclipse CDT. I've downloaded MinGW from their website. I get this error when I'm compiling:</p>
  
  <blockquote>
    <p>c:\mingw\bin../lib/gcc/mingw32/4.6.1/include/c++/cwchar:250:11:
    error: '::wcstold' has not been declared
    c:\mingw\bin../lib/gcc/mingw32/4.6.1/include/c++/cwchar:266:22:
    error: '__gnu_cxx::wcstold' has not been declared</p>
  </blockquote>
  
  <p>Why are they not defined? Is there something I forgot to include?</p>
