# This file goes with hidden_test_main.c and hidden_test_1.c.
# The main program defines several symbols with each of the ELF
# visibilities, and the shared library attempts to reference the
# symbols.  We try to link the program and check that the expected
# error messages are issued for the references to internal and
# hidden symbols.  The errors will be found in hidden_test.err.
