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