I did what I always did.

Did I forget a specific 64 bit option?
No, this is due to changes in the C standard. The relevant definition
in lisp.h is guarded like this:
#if (!defined (__STDC_VERSION__) || __STDC_VERSION__ < 201112L) && \
(!defined (__cplusplus) || __cplusplus < 201103L)
/* No type has a greater alignment requirement than max_align_t.
(except perhaps for types we don't use, like long double) */
typedef union
{
struct { long l; } l;
struct { void *p; } p;
struct { void (*f)(void); } f;
struct { double d; } d;
} max_align_t;
#endif
Are you building with sources older than the addition of the #if?
