------- Additional Comments From dir at lanl dot gov 2005-03-14 18:05 ------- This option is needed with most codes decended from main frame codes because almost all compiliers for the main frames did something like "-finit-local-zero" by default. The widely used suite of finite element codes from Livermore - DYNA3D, DYNA2D, NIKE2D, NIKE3D, TOPAZ2D, TOPAZ3D, MAZE, INGRID, ORIAN and TAURUS all require this option. Going through hundreds of thousands of lines of codes and trying to patch it to work with out "-finit-local-zero" is hopeless.
