It's C99 ;-)  The comment in utils_base.c was fixed in SVN already, I
fixed the comment in check_disk.c now, too.  Thanks for noting this.

I guess UnixWare needs "-lsocket -lnsl" on the linker command line, you
could try setting LIBS="-lsocket -lnsl" in the environment.  Then, run
"make distclean" before calling "./configure" again.  If that solves the
problem I don't understand why the "./configure" script wasn't able to
figure that out automagically, though (it tries to do so).
