Ok, no questions. That's all I wanted to know.

Bug #5963: MacOS < 10.6 has no memalign

I use definition of `aligned_malloc` from trunk in a st_pool_allocation patch for ruby_1_9_3,
and I have report from a man who has OS X 10.5.8 , that there is such error:

   pool_alloc.inc.h:55:2: error: #error no memalign function

It seems that OS X before 10.6 had no memalign or posix_memalign function.
Possibly `valloc` could be used with similar HEAP_ALIGN_LOG determination as done for OpenBSD in http://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/34404

As you can see, it is not possible to choose different version of MacOS here:
