Emacs on Windows sets EMACSDATA (and also EMACSLOADPATH, EMACSDOC and
EMACSPATH) at startup, to account for the possible move of the
installation tree between the build and the run time.  This is
because, unlike on Unix, the Windows build does not fix the
installation directory at build time.

I think "M-x setenv" would be better.

No, it's not strange.

That's not a good idea: some Makefile's set EMACS* variables
themselves.  I will try to find another way to avoid pollution of
process-environment, though.  Thanks for pointing this out.
