  26 # The main program defines several symbols with each of the ELF
  27 # visibilities, and the shared library attempts to reference the
  28 # symbols.  We try to link the program and check that the expected
  29 # error messages are issued for the references to internal and
  30 # hidden symbols.  The errors will be found in hidden_test.err.
