+=nt/INSTALL.w64= provides detailed instructions for compiling Emacs on
+recent Windows versions.  Here are some additional steps I had to
+figure out on my own:
+* Mingw-w64
+- Set =$HOME= to =%HOMEPATH%= by changing =db_home= to =windows= in
+  =c:/msys64/etc/fstab=.
+- In addition to =c:\msys64\mingw64\bin=, adding =c:\msys64\usr\bin=
+  to the system =PATH= allows Emacs to access applications installed
+  with =pacman=.
+  - It's not obvious whether the Mingw-w64 =PATH= entries should go
+    last (in which case Emacs will pick the wrong ~find~ command) or
+    first (in which case… /everything else/ will pick the wrong ~find~
+    command?).  At least Emacs has a variable to configure
+    (~find-program~).
+* Compiling
+Make sure to specify ~-c core.autocrlf=false~ *when cloning* the Emacs
+repository; ~autogen.sh~ gets confused otherwise.
+* Configuring
+AFAICT one must set the variable ~shell-file-name~ explicitly to
+=c:/msys64/usr/bin/bash.exe=, otherwise Emacs's Windows-specific
+initialization logic uses a built-in shell ersatz (=nt/cmdproxy.c=).
+** TODO =HOME=
+Went with the instructions from [[info:emacs#MS-Windows Registry]]; could
+maybe use [[info:emacs#Windows HOME]] by setting =HOME= to =%HOMEPATH%=,
+to avoid having to spell out my username?
