GCC can help, at least to an extent. See "man gcc":
...
    -Wcast-align
	Warn whenever a pointer is cast such that the required alignment
	of the target is increased.  For example, warn if a "char *" is
	cast to an "int *" on machines where integers can only be
	accessed at two- or four-byte boundaries.
