1.
If you have cygwin installed ( https://www.cygwin.com/ ),
sed is available as a pre-built package which you can easily install.
They currently have sed-4.4 packaged, but I'm sure they will soon
have sed-4.7.


2.
Similarly, if you have cygwin installed, sed can be built from
sources. Installing the "xz","make","gcc" packages should suffice for
compiling sed from tar archive (compiling from git requires more
complicated setup and tools).

  wget https://ftp.gnu.org/gnu/sed/sed-4.7.tar.xz
  tar -xf sed-4.7.tar.xz
  cd sed-4.7
  ./configure
  make

The resulting binary will require the cygwin environment (or at least
the cygwin1.dll file to be available).


3.
With cygwin (and with most gnu/linuxes), the MingW cross-compiler can
be used to build sed binaries that can "just work" on any windows
machine without requiring cygwin1.dll.
There are two common "flavors" for MingW:

   i686-w64-mingw32   = builds 32bit (PE32) executables
   x86_64-w64-mingw32 = builds 64bit (PE32+) executables

On Cygwin the packages are: mingw64-i686-gcc-core  mingw64-x86_64-gcc-core

On Debian the packages are: gcc-mingw-w64-i686 gcc-mingw-w64-x86-64

Installing these packages should automatically pull all the required
dependencies (i.e. many more packages).

Then, to build sed using 32bit mingw, use the following commands:

  wget https://ftp.gnu.org/gnu/sed/sed-4.7.tar.xz
  tar -xf sed-4.7.tar.xz
  cd sed-4.7
  ./configure --disable-nls --host=i686-w64-mingw32
  make

Replace "--host=i686-w64-mingw32" with "--host=x86_64-w64-mingw32"
to build a "sed.exe" binary for 64bit.

NOTE:
The later stages of such builds might fail with errors mentioning
"lib/netinet/in.h". If you see this failure, it happens *after*
sed.exe was already successfully built, so the error can safely ignored.


4.
I do not know (and not familiar with) building sed using native windows
tools (e.g. Microsoft Visual Studio).
If anyone has experience with such builds, please do send information.


5.
In case you don't have cygwin/mingw and you just want a working sed
on native windows, I've compiled sed-4.7 for 32bit and 64bit
using the exact instructions in step 3.
They are available here:

https://download-mirror.savannah.gnu.org/releases/sed/sed-4.7-64bit.exe
https://download-mirror.savannah.gnu.org/releases/sed/sed-4.7-32bit.exe

The checksum for these binaries:

  $ sha1sum sed-4.7-32bit.exe sed-4.7-64bit.exe
  be5b6e0a4c025703431d49d3c156b07caaecb327  sed-4.7-32bit.exe
  b4b4c888f3e2fd950ac41f779d4e5608081da32a  sed-4.7-64bit.exe

  $ sha256sum sed-4.7-32bit.exe sed-4.7-64bit.exe
  89de8ab100b2b42fae1730db9b337ace77270b024958119a6d304abe7cc4b703 
sed-4.7-32bit.exe
