This is not C++ syntax; it is an extension of the GNU compiler which  
is supported by many other compilers as well.  Apparently it is not  
supported by the compiler you are using.  We could either add  
autoconf magic to find out whether the compiler supports the extended  
syntax, or add a check for your compiler.  Can you tell me how to  
identify your compiler using #ifdef?
