189: * This is strictly a core-economy kluge. The really clean way to handle
190: * compilation is to slurp the whole file into core and then do all the
191: * name-collision checks and entry writes in one swell foop. But the
192: * terminfo master file is large enough that some core-poor systems swap
193: * like crazy when you compile it this way...there have been reports of
194: * this process taking *three hours*, rather than the twenty seconds or
195: * less typical on my development box.
196: *
197: * So. This hook *immediately* writes out the referenced entry if it
198: * has no use capabilities. The compiler main loop refrains from
199: * adding the entry to the in-core list when this hook fires. If some
200: * other entry later needs to reference an entry that got written
201: * immediately, that's OK; the resolution code will fetch it off disk
202: * when it can't find it in core.
203: *
204: * Name collisions will still be detected, just not as cleanly. The
205: * write_entry() code complains before overwriting an entry that
206: * postdates the time of tic's first call to write_entry(). Thus
207: * it will complain about overwriting entries newly made during the
208: * tic run, but not about overwriting ones that predate it.
209: *
210: * The reason this is a hook, and not in line with the rest of the
211: * compiler code, is that the support for termcap fallback cannot assume
212: * it has anywhere to spool out these entries!
213: *
214: * The _nc_set_type() call here requires a compensating one in
215: * _nc_parse_entry().
216: *
217: * If you define HAVE_BIG_CORE, you'll disable this kluge. This will
218: * make tic a bit faster (because the resolution code won't have to do
219: * disk I/O nearly as often).
