remove -Wcast-align from --enable-warnings
I originally added this warning option based on a misunderstanding of how it works. it does not warn whenever the destination of the cast has stricter alignment; it only warns in cases where misaligned dereference could lead to a fault. thus, it's essentially a no-op for i386, which had me wrongly believing the code was clean for this warning level. on other archs, numerous diagnostic messages are produced, and all of them are false-positives, so it's better just not to use it.
