This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

The problem is in the generated ../emacs-24.0.93/src/makefile, which
has the following target and associated rule:

globals.h: gl-stamp
      @cmd /c rem true

In an MinGW/MSYS bash shell, this rule invokes the MS Windows cmd.exe
command interpreter, which issues a prompt and then does not exit, thereby
halting the build.  The output from make looks like this, at this point:

echo timestamp > gl-stamp
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

c:\emacs-24.0.93\src>

Entering "exit" at the prompt causes the Windows cmd.exe to exit
resulting in the make build resuming.  (NOTE: a build of the candidate
release for Emacs 23.4 does not have the problem.)

It appears that the above rule for the target globals.h
is an error.

FYI, I invoked configure.bat like this

cmd /c "configure.bat --cflags -fno-omit-frame-pointer --cflags -IC:/usr/include"

within a MinGW/MSYS bash shell. It reported the following:

This is a known issue with the MSYS Bash.  That shell is not supported
by the Windows build of Emacs, for this very reason, see nt/INSTALL.

Just remove MSYS from your PATH, and you should be able to build EMacs
just fine.  You don't need a Unixy shell.

I'm closing this bug report.

Thanks for reporting and digging into this.
