BTW, shouldn't the line in mutex.inl that reads
OSVERSIONINFO version_info = {sizeof(OSVERSIONINFO)};
This is an idiomatic way to initialize the first member to 
sizeof(OSVERSIONINFO) and the rest to zero.
Ah, ok. So GCC shouldn't emit those missing initializer warnings. Would 
be nice to silence them anyway, though. Maybe using

     OSVERSIONINFO version_info = {sizeof(OSVERSIONINFO), 0, 0, 0, 0, 0};

?

be replaced with
OSVERSIONINFO version_info;
    version_info.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
This initializes dwOSVersionInfoSize to sizeof(OSVERSIONINFO) and leaves the 
rest uninitialized.
Not a problem if the return value of GetVersionEx() is checked.
