They should be identical.  XQuartz installs to /opt/X11 and sets up the /usr/X11 symlink.  There was a bug in the 10.9.0 and 10.9.1 installer (fixed in the 10.9.2 and later versions) that accidentally reinstalled the stubs even if XQuartz was already installed on the system.

This was discussed on x11-users last year, and users were recommended to reinstall XQuartz after upgrading to those versions of Mavericks.  Most users upgraded anyways because we released a new version of XQuartz around that time anyways.

The XQuartz installer will remove the stubs and install the /usr/X11 symlink. The sole purpose of the stubs is to allow legacy applications that link against /usr/X11/lib to trigger the X11redirect app which just prompts users to install XQuartz.  Building against those stubs isn't really supported.

I looked at your aclocal.m4 changes for this.  You should just check pkg-config results.  If the user tries to build against the /usr/X11 stubs, they'll be informed that X11 isn't installed at that location.  With the symlink pointing to the installed XQuartz, they'd get the correct pkg-config data.
