  17 # GDB tests for names beginning with '$'
  18
  19 # This is aimed at HP-UX systems where a lot of system
  20 # routines and names begin with '$' or '$$'.  GDB 4.16 was
  21 # unable to deal with these names as they clashed with
  22 # convenience variables.  Wildebeest should accept such
  23 # names in preference to convenience variables.
