After doing a build of emacs on Windows with MinGW (configure, make bootstrap,
.., make install) I found that then doing a make clean, make failed.
Specifically: there was an "access denied" message for temacs.exe during the
make step. (I'm new to building emacs on Windows but presumably a make clean,
make after the original build should work).
After a little poking around I discovered that the problem is that during the
build a dummy temacs.exe file is being created with only rw permissions (see
lib-src/makefile).
Later in the build, when temacs.exe is created from temacs.bin by using
addsection, apparently the permissions (rw) from the existing temacs.exe file
are kept thus resulting in a temacs.exe file without executable permission.
So: the simple fix I've done is to delete any existing temacs.exe file just
before using addsection to create the file.
The attachment with a fix is a diff -u against the current HEAD
src/makefile.w32-in (revision 1.56).

I'm confused, what permissions are you talking about? Windows does not
use POSIX permissions, all readable .exe files are considered executable.

I'm not really familiar with the details of Windows file permissions
so the easiest way for me to respond is to say that in
my Windows environment (see below) a 'mingw32-make clean'
followed by a 'mingw32-make' fails with a
'permission denied' for temacs.exe.

-------------------------------------------------------------
My environment (which I think is nothing out of the ordinary)
Windows XP (patched) using NTFS file structure
MinGW (for gcc, mingw32-make & etc)
Cygwin (for bash & etc)
-------------------------------------------------------------
As described previously, some poking around shows that the
problem is due to the fact that a dummy temacs.exe file
without 'execute' permission exists
when addsection is run in src/makefile.
The dummy file is created in lib-src/makefile.
The simple solution to the problem is to delete the dummy file
just before runing addsection to create the real
temacs.exe.
I've attached a patch to do this against the EMACS_22_BASE
src/makefile.w32-in

Since the offending command is an echo, which is a shell built-in, which
shell are you using to build Emacs? It seems to be one that we haven't
encountered before, so there may be other problems.

Nothing special: A current cygwin bash (invoked as 'sh') ....
$mingw32-make which-sh
[Please ignore a syntax error on the next line - it is intentional]
/usr/bin/sh: -c: line 0: unexpected EOF while looking for matching `"'
/usr/bin/sh: -c: line 1: syntax error: unexpected end of file
Using c:/cygwin/bin/sh.exe as shell.
c:/cygwin/bin/sh.exe --version
GNU bash, version 3.2.33(18)-release (i686-pc-cygwin)
Copyright (C) 2007 Free Software Foundation, Inc.
[For the above: '$(SHELL) --version' added to the cmds for
the which-sh target ....]
Please note that once I apply the patch to delete the dummy temacs.exe
file, 'mingw32-make clean' / 'mingw32-make' works just fine and gives
me a working Windows emacs.

I've just checked in a different patch, to disable the Cygwin misfeature
of trying to map unix file permissions onto NTFS ACLs. This should avoid
any other such problems that might be lurking, now and in the future.
