- The following comment is not correct anymore. AIX has a trap signal
- that might be sent with a "stopped after a load" status. This might
- show up when the inferior is just started, or anytime inferior
- loads something else. It is incorrect to try to skip over it *only* in
- startup-time. It always has to be ignored and should not be mixed up
- with breakpoint traps. See the macro SIGTRAP_STOP_AFTER_LOAD and its
- usage in infrun.c.
