http://bugs.winehq.org/show_bug.cgi?id=16968

Summary: environment variables not passed across to commands that
                    are run with popen
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

this is the python test from test_os.py, but it should work equally
as well in straight c-code.  the only reason this test _happened_
to be run at all is because i have msys installed.  normally, under
windows, this test would be entirely skipped.

    def test_update2(self):
        if os.path.exists("/bin/sh"):
            os.environ.update(HELLO="World")
            value = os.popen("/bin/sh -c 'echo $HELLO'").read().strip()
            self.assertEquals(value, "World")
