bug#21590: 25.0.50; MS-Windows; fns.c:4863:21: error: 'MD5_DIGEST_SIZE' undeclared (first use in this function)

[Keith David Bershatsky]

I am trying to build Emacs on MS-Windows with support for images (and hopefully 
XPM too), using a combination of MinGW and GnuWin32.

MinGW has the following four (4) installations:

    mingw-get install mingw32-base

    mingw-get install msys-base

    mingw-get install autoconf

    mingw-get install automake

And, I ran the following from a MinGW shell:  mount c:/mingw /mingw

GnuWin32 has everything that comes with `download.bat`, with the extras offered 
during install, followed by `install c:\gnuwin32`

The recipe that I am using to build is as follows:

    export CPPFLAGS="-I/c/gnuwin32/include"

    export LDFLAGS="-L/c/gnuwin32/lib"

    export PATH=/c/mingw/bin:/c/mingw/msys/1.0/bin:/c/gnuwin32/bin

    ./autogen.sh

    ./configure --prefix=/c/docume~1/lawlist/desktop/trunk

    make
