/* Alignment, in bits, a C conformant malloc implementation has to provide. The HP-UX malloc implementation provides a default alignment of 8 bytes. This can be increased with mallopt. The glibc implementation also provides 8-byte alignment. Note that this isn't enough for various POSIX types such as pthread_mutex_t. However, since we no longer need the 16-byte alignment for atomic operations, we ignore the nominal alignment specified for these types. The same is true for long double on 64-bit HP-UX. */
If PA malloc doesn't actually provide 16-byte alignment, this change seems problematic; it will mean any type that wants 16-byte alignment will silently get 8-byte alignment instead. Jason
