Try the following :
 
  Procedure Clrscrn;
  Pragma Interface(C, Clrscrn);
  Pragma Interface_Name(Clrscn,"_Clrscrn");

The last argument of Interface_Name is a string which denotes the name
of the external subprogram as defined in the other language (in
this case C).  The first argument is the name by which the subprogram 
is known to Ada.  I'll assumme that Meridian Ada supports this...
