+ (resolve_fl_namelist): Call it twice to check for host

! PR16404 test 6 - If a component of a derived type is of a type declared to
! be private, either the derived type definition must contain the PRIVATE
! statement, or the derived type must be private.
! Modified on 20051105 to test PR24534.
+! Modified on 20090419 to use -std=f95, since F2003 allows public types
