And it still failed on Linux, since glibc won't even flush input streams
on fclose.  But rather than write rpl_fclose, I think the simpler fix is
just explicitly flushing as part of close_stdin, seeing as how so few
programs actually need to flush stdin on exit.  At which point, the m4
test that triggered this jaunt passes on Linux again (or skips, if you are
still using too-old sed).

        Work around glibc's failure to flush stdin on fclose.
        * lib/closein.c (close_stdin): Flush stdin before closing.

Don't work too hard, make some time for fun as well!
