220      * name-collision checks and entry writes in one swell foop.  But the
221      * terminfo master file is large enough that some core-poor systems swap
222      * like crazy when you compile it this way...there have been reports of
223      * this process taking *three hours*, rather than the twenty seconds or
224      * less typical on my development box.
225      *
226      * So.  This hook *immediately* writes out the referenced entry if it
227      * has no use capabilities.  The compiler main loop refrains from
228      * adding the entry to the in-core list when this hook fires.  If some
229      * other entry later needs to reference an entry that got written
230      * immediately, that's OK; the resolution code will fetch it off disk
231      * when it can't find it in core.
232      *
233      * Name collisions will still be detected, just not as cleanly.  The
234      * write_entry() code complains before overwriting an entry that
235      * postdates the time of tic's first call to write_entry().  Thus
236      * it will complain about overwriting entries newly made during the
237      * tic run, but not about overwriting ones that predate it.
238      *
239      * The reason this is a hook, and not in line with the rest of the
240      * compiler code, is that the support for termcap fallback cannot assume
241      * it has anywhere to spool out these entries!
242      *
243      * The _nc_set_type() call here requires a compensating one in
244      * _nc_parse_entry().
245      *
246      * If you define HAVE_BIG_CORE, you'll disable this kluge.  This will
247      * make tic a bit faster (because the resolution code won't have to do
248      * disk I/O nearly as often).
