Hi,
During compilation of some bluetooth apps I get lots of warings like this:

In file included from /usr/include/sys/socket.h:35,
                 from connectiondlg.h:31,
                 from connectiondlg.cpp:24:
/usr/include/bits/socket.h:91: warning: `PF_BLUETOOTH' redefined
/usr/include/bluetooth/bluetooth.h:43: warning: this is the location of the previous definition
/usr/include/bits/socket.h:123: warning: `AF_BLUETOOTH' redefined
/usr/include/bluetooth/bluetooth.h:42: warning: this is the location of the previous definition
In file included from connectiondlg.h:35,
                 from connectiondlg.cpp:24:
/usr/include/bluetooth/hci.h:482: warning: ANSI C++ forbids zero-size array `condition'
/usr/include/bluetooth/hci.h:909: warning: ANSI C++ forbids zero-size array `data'

/usr/include/bluetooth/hci.h:1058: warning: ANSI C++ forbids zero-size array `conn_info'

Would be nice if bluetooth.h would not override stuff already defined

sys/socket.h:123:#define AF_BLUETOOTH    PF_BLUETOOTH

I would suggest that bluetooth.h includes itself sys/socket.h before checking if AF_BLUETOOTH
is defined.   This removed the dependency on how headers are ordered in source files.
Works for me ;)

hci.h may be due to old g++2.94.4 used on debian.  No idea about a workaround :(
