I don't see this in Emacs 25.2, and I don't have the current master
installed to test there.  So maybe this is a new thing on master.

I had to "touch /path/to/emacs/lisp/files/*.elc" after installation to fix
it.

??? Do you mean that compressing files with gzip doesn't preserve
their time stamps?  It does here.  The gzip manual specifically says:

     `gzip' reduces the size of the named files using Lempel-Ziv coding
  (LZ77).  Whenever possible, each file is replaced by one with the
  extension `.gz', while keeping the same ownership modes, access and
  modification times.

What version of gzip did you use?

Ok, you are right. There is a version 1.6 of gzip.exe  distributed with
TeXLive that has interfered here.
It doesn't preserve timestamps when compressing files. This is definitely a
problem, but not in emacs.

The 1.8 gzip.exe from MSYS2 does preserve timestamps.

Sorry for the noise.

Heh, I have MSYS Gzip 1.3.5 and GnuWin32 Gzip 1.2.4 here, and they
both preserve timestamps.  So I guess what you have is some botched
port of Gzip.

No sweat.  Closing.
