No. It's not needed all that much, since you can find the alignment
of a type in C.
#include <stddef.h>
#define alignof(type) offsetof (struct { char x; type y; }, y)
It wouldn't be hard to add an AC_CHECK_ALIGNOF macro, which would work
like AC_CHECK_SIZEOF. The only real advantage of this would be that
you could use the alignments in #if expressions.
