FWIWn I build Emacs trunk with a standard, not hacked, MSYS2/MingW64.
I update trunk regularly, but I update MSYS2/MingW64 too (with 'pacman -
Syu').
So nowadays, to build trunk, this is what I do :

$ build_alias=x86_64-w64-mingw32 make -j 8 bootstrap

(bootstrap optional).

I'm not sure that the MingW64 changes needed to the configure script can 
be found in another place than emacs trunk (aka : 24.4).
