Thank you. You are right.

The gdb comes with apple has '-arch' option, but gdb 7.0 does not.

$ /usr/bin/gdb --help
--translate Debug applications running under translation.
-arch i386|armv6|x86_64|ppc Specify a gdb targetting a specific
architecture

So should I do what Joel Brobecker suggested in adding that option in
gdb/main.c?

Thank you.
