I honestly have 0 idea how it is not 8-aligned right now (nor how its
size is 32 and not like 56), given that this is its definition...
no, strike that, I see that there are *two* versions of
struct___pthread_mutex.h, one in sysdeps/mach/hurd/htl/bits and the
other one in sysdeps/htl/bits/types, and the former one wins. The
latter one seems unused then, its only point was to confuse the hell
out of me.
