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.
/* In aix, number of the trap signals we need to skip over once the
inferior process starts running is different in version 3.1 and 3.2.
This will be 2 for version 3.1x, 3 for version 3.2x. */

Himm.., recently we nullified trampoline entry names in order not
to confuse them with real symbols. Appearently this turned into a
problem, and msymbol vector did not get relocated properly. If
msymbols have to have non-null names, then we should name
trampoline entries with empty strings.

We don't have a valid `objfile' at this point. This is moved into the
previous statement; ALL_OBJFILES() for-loop.
