While I could not reproduce the problem on both, GCC 3.4.6
and GCC 4.1.0, the suggested change won't hurt in either
case, so I applied it.

gcc 3.4.5 (comes with WinAVR 20060125) complains when using ISR(...) in C++:

usart.cpp:179: warning: `_Z11__vector_25v' appears to be a misspelled signal handler

i.e., it mangles the name despite the <extern "C">; this can be fixed by changing the definition of ISR for C++ from

#define ISR(vector) \
extern "C" void vector(void); \
void vector (void) _attribute_ ((signal)); \
void vector (void)

to

#define ISR(vector) \
extern "C" void vector (void) _attribute_ ((signal)); \
void vector (void)

However, I don't know if this is compatible with other versions of gcc.
