I don't know if this report belongs here or if I should report a 
binutils bug, but I'll start here.

When building emacs-w32.exe with the current binutils, I end up with an 
executable that won't run after it's stripped (at least on x86_64).  I 
traced this to the fact that emacs-w32 comes with its own manifest.  My 
understanding is that the emacs-w32 manifest should take precedence over 
the Cygwin default manifest, but something's going wrong in this case.

Here's a simple test case to illustrate the problem, using a slight 
modification of the resource file that comes with emacs, and the 
corresponding manifest (see attached).

$ windres -O coff emacs.rc -o emacs.res

$ cat test.c
int main()
{
   return 0;
}

$ gcc -o test test.c -Wl,emacs.res

$ strip test.exe

$ ./test.exe
bash: ./test.exe: cannot execute binary file

The stripped binary has a messed up .rsrc section:

$ objdump -j .rsrc -s test.exe

test.exe:     file format pei-x86-64

Contents of section .rsrc:
objdump: Reading section failed
