I think it's better to do this:

take_argv_t = function (parms: Pcmd_parms; mconfig: Pointer;  
argc:cint; argv: PPChar): PChar; cdecl;

You can still index it as an array in FPC, but it's clearer what the  
actual type is that gets passed (an "array of pchar" is the same as a  
double pointer to char in C). I was indeed wrong about the varargs  
stuff I said earlier, for some reason I had read "array of pchar" as  
"array of const".
