sdbout.c (preinit_symbols, [...]): New statics.

Browse Source 
* 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.
