modification history
--------------------
01f,09apr98,dbt increased stack size for solaris simulator.
01e,15nov95,jcf renamed vxColor2.h to vxColor.h.  sigh.
01d,15nov95,jcf renamed vxColor.h to vxColor2.h.
01c,27sep95,jco re coding convention revision, removed rev field in GNODE.
01b,06sep95,p_m fixed coding convention problems.
01a,03aug95,jco written.
