+ * aclocal.m4: Include ../bfd/aclocal.m4.
+ * configure.in: Add stdlib.h to AC_CHECK_HEADERS. Call
+ BFD_NEED_DECLARATION on malloc, realloc, and free.
+ * acconfig.h: Add NEED_DECLARATION_MALLOC,
+ NEED_DECLARATION_REALLOC, and NEED_DECLARATION_FREE.
+ * configure, config.in: Rebuild.
+ * defs.h: Include <stddef.h> and <stdlib.h> based on HAVE_*_H
+ rather than __STDC__. Only declare malloc, realloc, and free if
+ NEED_DECLARATION_* is defined.
