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.
