Thomas E. Dickey ee8861cb49 ncurses 6.2 - patch 20201114 
+ fix some compiler-warnings in experimental Windows-10 driver.
+ modify a check for parameters in terminfo capabilities to handle the
  special case where short extended capability strings were not
  converted from terminfo to termcap format.
+ modify CF_MIXEDCASE_FILENAMES macro, adding darwin as special case
  when cross-compiling (report by Eli Rykoff).

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