Re: dnscurve updates

after looking at
http://www.opengroup.org/onlinepubs/000095399/functions/posix_memalign.html

one wonders, esp. since its only needed for command line tools, if the following
wouldn't do the trick by simply ignoring the alignment request:

#ifndef HAVE_POSIX_MEMALIGN /*or equivalent*/
/* int posix_memalign(void **memptr, size_t alignment, size_t size); */
#define posix_memalign(mp,a,s) (((*mp = malloc(s)) == 0 ) ? errno : 0)
#endif

What alternatives (to ignoring alignment) exist? malloc() until you
get one that is aligned right? The requirement that posix_memalign's
memory can go to free() rules out wrappers that get too much and then
return the first aligned address within.
