IIUC, this bit seems to cause problems on hydra:

http://hydra.nixos.org/build/10801925

./temacs: error while loading shared libraries: libz.so.1:
   cannot open shared object file: No such file or directory

Cf
http://hydra.nixos.org/build/10777061

which worked.

Thanks for mentioning that.  When linking to a shared library X one 
shouldn't need to explicitly link to all libraries that X itself links 
to.  But I suppose if hydra has the problem others will too, so I 
installed a patch to try to work around the problem, as emacs-24 bzr 117057.

It's made no difference:

http://hydra.nixos.org/build/10820711

Perhaps that change was not appropriate for emacs-24, since it was not
fixing any kind of bug.

It is fixing bugs, just not bugs that have been reported yet.  Evidently 
the fix is more hassle than it's worth on emacs-24, though, so I 
reverted it just now.

I would like to remind  osx users that this change might cause build to
fail if HomeBrew (with libpng) or XQuartz is installed, unset PATH before
running ./configure so that libpng-config won't interfere.

A question about code around line 5919 of image.c,
Shouldn't this if conditional wrap the last line in?


	  /* We use the current frame background, ignoring any default
	     background color set by the image.  */
#if defined (HAVE_X_WINDOWS) || defined (HAVE_NTGUI)
	  XColor color;
	  png_color_16 frame_background;

	  color.pixel = FRAME_BACKGROUND_PIXEL (f);
	  x_query_color (f, &color);

	  memset (&frame_background, 0, sizeof frame_background);
	  frame_background.red = color.red >> shift;
	  frame_background.green = color.green >> shift;
	  frame_background.blue = color.blue >> shift;
#endif /* HAVE_X_WINDOWS */

	  fn_png_set_background (png_ptr, &frame_background,
				 PNG_BACKGROUND_GAMMA_SCREEN, 0, 1.0);
