Stop supporting systems that don't have mmap(3).
Drop the obsolete names_check() now that we deleted MLINKS.

About mdocml, the portable mandoc distribution
----------------------------------------------
a "manpath" line for each directory tree, and the order of these
lines meets your wishes.
-7. If you compiled with database support, run the command "sudo
+7. Run the command "sudo
makewhatis" to build mandoc.db(5) databases in all the directory
trees configured in step 6. Whenever installing new manual pages,
re-run makewhatis(8) to update the databases, or apropos(1) will
Understanding mandoc dependencies
---------------------------------
-The mandoc(1), man(1), and demandoc(1) utilities only depend
-on the zlib library for decompressing gzipped manual pages,
-but makewhatis(8) and apropos(1) depend on the following
-additional software:
-
-1. The SQLite database system, see <http://sqlite.org/>.
-The recommended version of SQLite is 3.8.4.3 or newer. The mandoc
-toolset is known to work with version 3.7.5 or newer. Versions
-older than 3.8.3 may not achieve full performance due to the
-missing SQLITE_DETERMINISTIC optimization flag. Versions older
-than 3.8.0 may not show full error information if opening a database
-fails due to the missing sqlite3_errstr() API. Both are very minor
-problems, apropos(1) is fully usable with SQLite 3.7.5. Versions
-older than 3.7.5 may or may not work, they have not been tested.
+The following libraries are required:
+
+1. zlib for decompressing gzipped manual pages.
2. The fts(3) directory traversion functions.
If your system does not have them, the bundled compatibility version

Many issues are annotated for difficulty as follows:
************************************************************************
- Why are we using MAP_SHARED, not MAP_PRIVATE for mmap(2)?
- How does SQLITE_CONFIG_PAGECACHE actually work? Document it!
from kristaps@ Sat, 09 Aug 2014 13:51:36 +0200
Several areas can be cleaned up to make mandoc even faster. These are
- struct mparse refactoring
Steffen Nurpmeso Thu, 04 Sep 2014 12:50:00 +0200
-- Consider creating some views that will make the database more
- readable from the sqlite3 shell. Consider using them to
- abstract from the database structure, too.
