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