Well, if you don't mind wasting a large amount of memory, try
the following (msotly untested) code...

/*
** round_up(amount, align) returns `amount' rounded up to the nearest
** alignment boundary.  `align' must be a power of 2.
*/
#define round_up(amount, align) ((((amount) - 1) | ((align) - 1)) + 1)

#define PAGESIZE 4096
#define memalign(size) round_up(malloc((size) + PAGESIZE), PAGESIZE)
