# 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.
