APAR status

• Closed as program error.

Error description

• When performing a build using IBM Rational ClearCase's clearmake
  utility, a large number of successive "+=" redefinition of a
  make macro may cause clearmake to use all available process
  memory and abort.
  
  This issue requires approximately 9,000 lines in the form of:
  
  BIG_MACRO += A lot more text to add to BIG_MACRO
  
  to be present in the makefile.
  
  The same makefile will successfully process using the current
  GNU make.
