Paths on Windows get confused since I use a strange combination of
some 4 different GNU/Linux-like systems on Windows (cygwin, msys2,
msys git, WSL).
Since Windows doesn't support symlinks properly, I can't use GNU Stow
to install my files. So for Windows I copy over all the necessary
files.
This way make won’t remove them after compilation is done. Normally
this might be useful, but in the case of Emacs Lisp being generated
from Org files, it’s really useful to have the original lisp files
after compiling them to elc files.
This stops Emacs complaining that some file is newer when the main
config depends on it. I don’t add a make dependency between them because
init.el doesn’t need to be recompiled when normal elisp files are
changed. Only when macros are involved.
