Sorry for the late answer.
L3P v1.4 has L3Version declared, v1.3 has not.
#ifdef (L3Version)
material { L3Color0 }
#else
#if (version >= 3.1) material #else texture #end { Color0 }
#end
(L3P v1.4 does not support PovRay < 3.1)
For the studs I suggest that you in the beginning of your file
declare L3Studs if not already declared/defined:
#ifndef (L3Studs)
#declare L3Studs = STUDS;
#end
and then just test for L3Studs.
