Emacs continues to support XP, I use it that way all the time.  I'm
guessing that you are using precompiled binaries from some site, and
those binaries were linked against system libraries which require
functions not present in the C runtime on XP.  (If these are official
GNU binaries, then it's unfortunate we provide such binaries.  In that
case, please file a bug report using report-emacs-bug.)

I think the root cause is that MinGW64 stopped supporting Windows XP.
This is probably justified in the 64-bit builds, but MinGW64 also
offers a 32-bit build environment, where XP should have been
supported.  FWIW, mingw.org's MinGW still supports Windows XP (and
also Windows 9X).
