Like this:

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

However, if you are looking for the optional image libraries, libxml2,
etc., you won't find them this way: Emacs loads them dynamically at
run time by using explicit LoadLibrary calls.  Maybe something like
this:

  stringgs emacs.exe | fgrep -i ".dll"
