        (I'm actually on netbsd-current)
        I get warnings while building errno.{so,po,o},
        building statically linked binaries (/sbin items) and so forth.
        they correctly use errno.h, not "extern int errno".
        is it expected behavior?

        also, warning during errno.o build has extra .o in it :-)
