A DLL can never be statically linked.

If you want to be sure whether or not your executables depend on that
DLL, use the "depends" tool, which you can download from the net --
just run it as in "depends emacs.exe" and it will show a window with
all the DLLs that the binary wants to load.  Or use objdump that you
already have, like this:

  objdump -x emacs.exe | fgrep "DLL Name:"

The latter only shows the names of the DLLs, not their absolute file
names.

If the above methods show that your binary depends on
libgcc_s_dw2-1.dll, you _must_ tell your users which one of them is
actually linked into the binary.  The "depends" tool will show you a
full path to the DLL which the binary will use, and the linker links
against the DLL which came with the version of GCC you used to compile
Emacs.  You should tell the users "get libgcc_s_dw2-1.dll from GCC
version 4.x.y that you find on this-and-that site".

Thanks.
