I've been building without HAVE_POSIX_MEMALIGN too, since a while
back, until I track down why using posix_memalign() has problems
on FreeBSD/amd64.

Can you try running `./configure' as usual, and then manually
setting HAVE_POSIX_MEMALIGN to:

    /* #undef HAVE_POSIX_MEMALIGN */

in src/config.h before running ``make bootstrap''?

Stefan Monnier is probably the best person to track this down,
before I manage to learn enough about memory allocation in Emacs,
so if you find that disabling posix_memalign() fixes the build
for you, please let Stefan know (he's already a subscriber to the
list, so Cc:'ing him may be unnecessary).
