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