 Unlike say x11/xinit, x11/sessreg's configure.ac and thus configure do not have
 
 XORG_PROG_RAWCPP
 
 Therefore the usual addition to the port Makefile of:
 
 TOOL_DEPENDS+=        tradcpp-[0-9]*:../../devel/tradcpp
 CONFIGURE_ENV+=        ac_cv_path_RAWCPP="${PREFIX}/bin/tradcpp -Uunix"
 
 does nothing to help x11/sessreg if using gcc5 on DragonFly 4.3-DEVELOPMENT.
