compile emacs version 26.1

Emacs version 26.1 was released yesterday, but there is no binary download for
Windows. Now it is time to compile it manually:

1. Download and install msys2 from https://sourceforge.net/projects/msys2/files/Base/x86_64

2. Run c:/msys64/msys2.exe and install necessary packages

   pacman -S --needed base-devel 
   mingw-w64-x86_64-toolchain 
   mingw-w64-x86_64-xpm-nox 
   mingw-w64-x86_64-libtiff 
   mingw-w64-x86_64-giflib 
   mingw-w64-x86_64-libpng 
   mingw-w64-x86_64-libjpeg-turbo 
   mingw-w64-x86_64-librsvg 
   mingw-w64-x86_64-lcms2 
   mingw-w64-x86_64-libxml2 
   mingw-w64-x86_64-gnutls 
   mingw-w64-x86_64-zlib
   

3. configure; make; make install

   ./autogen.sh
   PKG_CONFIG_PATH=/mingw64/lib/pkgconfig ./configure --without-imagemagick
   make
   make install prefix=/c/emacs
   

Now you can run emacs from C:/emacs/bin/runemacs

Quite easy 🙂
