dnl GNOME_X_CHECKS
dnl

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                          Solaris boxes have the library but not the header)
dnl   XPM_LIBS               -lXpm if Xpm library is present, otherwise ""
