# GDB tests for names beginning with '$'

# This is aimed at HP-UX systems where a lot of system
# routines and names begin with '$' or '$$'.  GDB 4.16 was
# unable to deal with these names as they clashed with
# convenience variables.  Wildebeest should accept such
# names in preference to convenience variables.
