* 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.
