That looks absolutely fine to me; indeed that syntax works just as
you and I both seem to expect, on my GNU/Linux box, (where I also have
grep-2.5.1).

Just a wild guess, (I can't verify it, because I don't use *any* tools
from cmd.exe, preferring the MSYS bash shell, and I use MSYS grep, not
the GnuWin32 variant, which I don't have), but since cmd.exe does not
perform the quote reduction the way a *nix shell would, grep has to do
that itself; it appears that it does so, for the RE pattern argument,
but maybe not for the globbed include pattern.  What happens, if you
omit the quotes in `--include=*.rec', or wrap the *entire* argument
in quotes, as `"--include=*.rec"'?

In any case, this looks like a bug in GnuWin32 grep.

Keith.

FWIW, this doesn't work with MSYS grep-2.4.2, since that doesn't
support the `--include' option.  Instead, I would use:

  find . -iname "*.rec" -exec grep -iH "version" {} +

(noting that this is a *nix compatible `find', *not* Microsoft's
 incompatible tool, of the same name).
