[Bug 19801] New: cygwin can't run a batch file from inside a shell script without explicit cmd /c

http://bugs.winehq.org/show_bug.cgi?id=19801

Summary: cygwin can't run a batch file from inside a shell
                    script without explicit cmd /c
           Product: Wine
           Version: 1.1.27
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Given the batch file foo.bat containing
  echo FOO
and the shell script 'foo.sh' containing
  ./foo.bat
the command
  ./foo.bat
interactively will output
  FOO
on both cygwin/windows and cygwin/wine, but the command
  sh foo.sh
will produce
  FOO
on cygwin/windows but will fail on cygwin/wine saying
  foo.sh: line 1: ./foo.bat: permission denied

This happens both in an interactive cygwin shell started under wineconsole,
as well as the naked command
$ wine ~/.wine/drive_c/cygwin/bin/sh foo.sh

which sometimes says permission denied, and sometimes says "bad address", e.g.

foo.sh: line 1: ./foo.bat: Bad address
     13 [main] sh 50! _cygtls::handle_exceptions: Error while dumping state
(probably corrupted stack)
foo.sh: line 1:    50 Segmentation fault      (core dumped) ./foo.bat

So the "permission denied" error might be a symptom of a crash, too.

This was found while trying to automate the chrome and firefox build
setup procedures.
