Do I need to increment the minor version when adding a new
cygwin_internal call?  It seems so:

2009-01-09  Christopher Faylor

        * include/sys/cygwin.h (CW_SETERRNO): Define.
        * external.cc (CW_SETERRNO): Implement.
        * include/cygwin/version.h: Bump CYGWIN_VERSION_API_MINOR to 192 to
        reflect the above change.
