Comment (by ezimanyi):

 I am really sorry to insist :-( but I am unable to find a solution to the
 problem. I have tried the following solution
 {{{
 PG_FUNCTION_INFO_V1(call_transform);
 /**
  * Call the PostGIS transform function
  */
 PGDLLEXPORT Datum
 call_transform(PG_FUNCTION_ARGS)
 {
         Datum result = CallerFInfoFunctionCall2(
                 transform, fcinfo->flinfo, InvalidOid,
                 PG_GETARG_DATUM(0), PG_GETARG_DATUM(1));

         /* Return null on null */
         if ( ! result )
                 PG_RETURN_NULL();

         PG_RETURN_DATUM(result);
 }

 /**
  * Transform the geometry to the given SRID
  */
 static Datum
 datum_transform(Datum value, Datum srid)
 {
         PG_RETURN_DATUM(DirectFunctionCall2Coll(call_transform,
 InvalidOid, value, srid));
 }
 }}}
 and the problem persist
