APAR status

• Closed as program error.

Error description

• The following errors might be seen when compiling a large test
  case:
  1540-1277 (S) The explicit template specialization "void
  parallelogram(Triangulation<2,2> &, const Point<2,double>
  (&)[2], const bool)" does not match any template.
   1540-0218 (S) The call does not match any parameter list for
  "parallelogram".
  

Local fix

• N/A
  

Problem summary

• PROBLEM DESCRIPTION: The overload resolution was not being done
  correctly due to different types 'unsigned' and 'signed' int.
  
  USERS AFFECTED: users with mixed overload resolution for
  unsigned and signed integers
  

Problem conclusion

• The compiler no longer gets confused over signed and unsigned
  int overload resolution.
  

Temporary fix
