can't compile Gnus under Cygwin

Hi,

It is reported that someone can't compile Gnus under Cygwin.

While compiling toplevel forms in file c:/home/gnus/lisp/earcon.el:
!! File error (("Searching for program" "no such file or directory" "/bin/sh"))

There is c:/cygwin/bin/sh.exe and it can be used as /bin/sh
normally, but it won't be found at the compile time.  Since I
don't have Cygwin, I'm not sure what's happened.  But it seems
that the use of `shell-command-to-string' in the top level is
harmful for compiling Gnus.  Is the attached patch acceptable?
If there's no objection, I'll commit it in Gnus CVS. :-)

	* gnus-art.el (gnus-treat-display-xface): Don't use
	`shell-command-to-string' when compiling.
	(gnus-treat-display-grey-xface): Ditto.
