# tests for namespaces
# Originally written by Satish Pai <pai@apollo.hp.com> 1997-07-23

# This file is part of the gdb testsuite

# Note: The original tests were geared to the HP aCC compiler,
# which has an idiosyncratic way of emitting debug info
# for namespaces.
# Note: As of 2000-06-03, they passed under g++ - djb
