191: * This is strictly a core-economy kluge. The really clean way to handle

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