+dnl GNOME_X_CHECKS
+dnl
+dnl Basic X11 related checks for X11.  At the end, the following will be
+dnl defined/changed:
+dnl   GTK_{CFLAGS,LIBS}      From AM_PATH_GTK
+dnl   CPPFLAGS		     Will include $X_CFLAGS
+dnl   GNOME_HAVE_SM	     `true' or `false' depending on whether session
+dnl                          management is available.  It is available if
+dnl                          both -lSM and X11/SM/SMlib.h exist.  (Some
+dnl                          Solaris boxes have the library but not the header)
+dnl   XPM_LIBS               -lXpm if Xpm library is present, otherwise ""
+dnl
+dnl The following configure cache variables are defined (but not used):
