incompatibility between g++ and vc++: Mutex

[Vincent Torri <torri@xxxxxxxxxxxxxxxxx>]

Hello,

i have another problem with this line: 

Mutex first & = &other < this ?  mutex_: other.mutex_;

There's an error with g++ (and none with vc++) : 
error: syntax error before `;' token

I don't understand why this does not work with a mutex.

Could someoe help me ?

Thanks !
