258 * This is strictly a core-economy kluge. The really clean way to handle
259 * compilation is to slurp the whole file into core and then do all the
260 * name-collision checks and entry writes in one swell foop. But the
261 * terminfo master file is large enough that some core-poor systems swap
262 * like crazy when you compile it this way...there have been reports of
263 * this process taking *three hours*, rather than the twenty seconds or
264 * less typical on my development box.
266 * So. This hook *immediately* writes out the referenced entry if it
267 * has no use capabilities. The compiler main loop refrains from
268 * adding the entry to the in-core list when this hook fires. If some
269 * other entry later needs to reference an entry that got written
270 * immediately, that's OK; the resolution code will fetch it off disk
271 * when it can't find it in core.
273 * Name collisions will still be detected, just not as cleanly. The
274 * write_entry() code complains before overwriting an entry that
275 * postdates the time of tic's first call to write_entry(). Thus
276 * it will complain about overwriting entries newly made during the
277 * tic run, but not about overwriting ones that predate it.
279 * The reason this is a hook, and not in line with the rest of the
280 * compiler code, is that the support for termcap fallback cannot assume
281 * it has anywhere to spool out these entries!
283 * The _nc_set_type() call here requires a compensating one in
286 * If you define HAVE_BIG_CORE, you'll disable this kluge. This will
287 * make tic a bit faster (because the resolution code won't have to do
288 * disk I/O nearly as often).
