Error description

• The following error occurs in test.f90 file when compiling with
  xlf:
  ----------------------------------------------------------------
  "test.f90", line 31.5: 1513-119 (S) Identifier array appeared in
  a USE statement but is not publicly accessible from this module.
  "test.f90", line 32.16: 1514-084 (S) Identifier tt is being
  declared with type name array which has not been defined in a
  derived type definition.

Local fix

• N/A
  

Problem summary

• USER AFFECTED:
  Users who specify USE ONLY to read in a type definition in a
  module indirectly through multiple levels of use association,
  where the type definition is guarded with the private attribute
  in one of the levels of use association,
  but ultimately is brought in as a public entity.
  
  PROBLEM DESCRIPTION:
  Compiler complains that an identifier is being declared with a
  type that is not publicly accessible.
  

Problem conclusion

• Fixed the frontend bug by marking the private/public attributes
  of the type definition being read properly.
  

Temporary fix
