  Changes between 0.9.7 and 0.9.7a  [XX xxx 2003]
 
+  *) IA-32 assembler support enhancements: unified ELF targets, support
+     for SCO/Caldera platforms, fix for Cygwin shared build.
+     [Andy Polyakov]

   *) Add support for FreeBSD on sparc64.  As a consequence, support for
      FreeBSD on non-x86 processors is separate from x86 processors on
      the config script, much like the NetBSD support.
