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

[Keith David Bershatsky <esq@lawlist.com>]

Thank you, Glenn, for the reference to the mail-list archives regarding moving `C:\gnuwin32\include\md5.h` out of the way.

Building the latest version of Emacs trunk master branch on Windows is by no stretch of the imagination as simple as the first Google search.  There is a reason that only one person in the entire world is posting Windows trunk builds every few weeks -- i.e., building Emacs on Windows is completely beyond the reach of mere mortals, and out of the reach of beginning programmers and hobbyists such as myself (without the assistance of advanced programmers such as you and Eli).

I renamed it to `md5.h.off` and tried my luck at building Emacs again, but was met with the error below.  I also tried my luck at building and incorporating into the `mingw` directory the following five (5) libraries -- zlib, giflib, libpng, jpeg and libpng -- in an effort to remove `gnuwin32` from the equation entirely; however, I was met with the same error message below.

Any additional help would sure be greatly appreciated.
