Comment (by bgamari):

 I ran a vanilla build of  on a fresh Windows instance and saw the
 following failures:
 {{{
 Unexpected results from:
 TEST="T15904 plugin-recomp-flags plugin-recomp-impure plugins09 plugins10
 plugins11"

 SUMMARY for test run started at 01/09/19 21:10:29 Greenwich Standard Time
  0:14:31 spent to go through
       23 total tests, which gave rise to
       67 test cases, of which
       32 were skipped

        6 unexpected failures

 Unexpected failures:

    plugins/plugins11.run             plugins11 [bad stdout] (normal)
    plugins/plugin-recomp-impure.run  plugin-recomp-impure [bad stdout]
 (normal)
    plugins/plugin-recomp-flags.run   plugin-recomp-flags [bad exit code]
 (normal)

 }}}
 Consequently I suspect few of these failures real.
