hello, my computer is configured in french, and gcc reports all the messages in french. Which is not very convenient when one want to search some info about the error with google. So i have 2 questions: 1) how to tell gcc that i want english error/warning messages ? (or what should i do to compile gcc so that its messages are in english) 2) in case there are french people who could answer, here is the message: leftturner.cpp:34: erreur: template (afin de rendre moins ambigue) est seulement permis a l'interieur des patron and the line 34 is : BufferWindow result( source.GetDimension().template Turn<1>(), source.GetEnvironment() ); thank you Vincent Torri
