# 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.
