I image you are using a git check out as source, instead I am using the 
tar-ball 
http://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-master.tar.gz. 
The cause of that SED failure seems the omission of 
"--enable-gcc-warnings=no" option. Indeed when I use

  PKG_CONFIG_PATH=/mingw64/lib/pkgconfig ./configure 
--without-imagemagick --enable-gcc-warnings=no

the output is
[...]
checking for ranlib... ranlib
checking for special C compiler options needed for large files... no
checking for _FILE_OFFSET_BITS value needed for large files... 64
checking whether gcc -I ./nt/inc accepts -g3 -O2... yes
checking whether the compiler is clang... no
checking whether C compiler handles -Werror -Wunknown-warning-option... no
checking whether make supports nested variables... (cached) yes
[...]

No SED failure.

Now all this seems strange because out of git check out, the option 
"--enable-gcc-warnings=no" should be enabled by default, if I understand 
some recent commit about it.. (It is YES, by default, in git check out, 
i think).

Maybe Paul has some idea about this..

 Ciao,
  Angelo.
