- new FSF address - removed a few hundred trailing spaces - fixed a few $Id$ lines - copied two license headers from *.hxx files to their respective *.cxx counterparts - added two test aps to .cvsignore - don't unlock an already unlocked mutex (Someone wanted to be on the safe side with this, but the result is undefined and makes pthread_mutex_destroy fail. Reference: manpage for pthread_mutexattr_gettype/The Open Group[1]: "Attempting to unlock a mutex of this type which is not locked results in undefined behaviour.") - re-enabled all subsystem destructors again (this has been disabled because fgfs hung on exit, due to the mutex destroy failure)
