The notes were quite extensive (in a TiddlyWiki,
http://www.tiddlywiki.com/), full of extensive build logs etc, they just
don't tell me which compiler I started with! The trouble was that
AdaCore's GNAT GPL 2009 (which is x86_64) doesn't work on Snow Leopard;
there was some problem ... AH! from 25 December 2009,

   GNAT seems to be OK (after installing XCode!)  Actually, that's only
   gcc-4.3.3. The GNAT-GPL-2009 and 6.2.2 compilers fall over because
   Darwin no longer exports sigreturn.
