-FUNCTION
-	bfd_preserve_save
-
-SYNOPSIS
-	bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
-
-DESCRIPTION
-	When testing an object for compatibility with a particular
-	target back-end, the back-end object_p function needs to set
-	up certain fields in the bfd on successfully recognizing the
-	object.  This typically happens in a piecemeal fashion, with
-	failures possible at many points.  On failure, the bfd is
-	supposed to be restored to its initial state, which is
-	virtually impossible.  However, restoring a subset of the bfd
-	state works in practice.  This function stores the subset and
-	reinitializes the bfd.
