Hmph.  I do not know what went wrong.  The one I had in /usr/bin
that came from the distro was too old that it didn't give any useful
result and failed, and that was why I got v0.5.0-207-g14964df
installed in ~/gitstuff/bin/ which is early on my $PATH; I do not
think I did any other updates but now I am seeing happy results.

        $ git checkout jk/bug-to-abort^1
        $ make SP_OBJ=usage.sp sparse
        GIT_VERSION = 2.13.0.3.g25cd291963
            SP usage.c
        usage.c:220:6: error: symbol 'BUG_fl' redeclared with diff...

And then with your fix, of course,

        $ git checkout jk/bug-to-abort
        $ make SP_OBJ=usage.sp sparse
        GIT_VERSION = 2.13.0.4.g3d7dd2d3b6
            SP usage.c

I am still puzzled but anyway now the problem is clearly on my end
and no longer reproduces, there is no reason to waste your time.

Sorry for the noise, and thanks for a fix again.
