sdbout.c (preinit_symbols, [...]): New statics.
* sdbout.c (preinit_symbols, sdbout_initialized): New statics.
(sdbout_symbol): If called before sdbout_init, queue DECL for
later and return.
(sdbout_init): Set sdbout_initialized true, process decls
queued earlier by sdbout_symbol.
(sdbout_finish): Use size_t for index variable.
