I didn't write "extern int errno".
It appears in already existing (now broken) code.

        ./gnome-1.0/gtk-xmhtml/XmHTMLI.h:extern int errno;
        ./errno.h:extern int errno;
        ./imap/os_aux.h:extern int errno;
        ./w3c-libwww/wwwsys.h:extern int errno;
        ./zutil.h:    extern int errno;
        ./kpathsea/c-errno.h:extern int errno;
        ./tcl-private/unix/tclUnixPort.h:extern int errno;
        ./mysql/my_sys.h:extern int errno;      /* declare errno */
        ./tk-private/unix/tkUnixPort.h:extern int errno;

for example.
