  Thanks. For simplicity, I feel tempted to remove:

PKG_CHECK_MODULES(APPDEFS, xt)
appdefaultdir=$(pkg-config --variable=appdefaultdir xt)
AC_SUBST(appdefaultdir)

from configure.ac, and "hardcode" Makefile.am to:

appdefaultdir = $(datadir)/X11/app-defaults

  This mainly, because in my computer I have "app-defaults"
directories in:

/etc/X11/app-defaults
/etc/X11/<choose-some-language>/app-defaults
/usr/X11R6/lib/X11/app-defaults
/usr/share/apps/kdisplay/app-defaults
/usr/share/app-defaults
/usr/share/X11/app-defaults
/usr/lib/app-defaults
/usr/lib/X11/app-defaults
/opt/kde3/share/apps/kdisplay/app-defaults
/usr/lib/<program-name>/app-defaults

  But probably better to have it easy to specify in
configure arguments, and "respect" the value configured
in libXt.
