I believe this shouldn't be necessary due to
https://git.savannah.gnu.org/cgit/hurd/gnumach.git/commit/?id=8e5e86fc13732b60d2e4d14152d92db1f1ae73f9 <https://git.savannah.gnu.org/cgit/hurd/gnumach.git/commit/?id=8e5e86fc13732b60d2e4d14152d92db1f1ae73f9> which forces mach_msg_type_t to always be 8 byte aligned. If you check the size before and after your patch, it will be the same.
you're right, I must have made this change before this commit.
