CMake's add_custom_target() can't track deps by itself.

Less spam on manpage indexers than with a symlink.

No longer gratis for Free Software.

Shipping two incompatible versions in the compiler's path is bleh...

It's used by another tool, and including the whole global header
has too many moving parts that go wrong.

Windows and Java can go to hell.  And all this code did was suppressing
a warning.

This includes splitting them to separate files, as cmake apparently
can't do shell scripting well.

No reason on our side, but it whines it wants to drop compat (while ancient
distributions still ship an old version).

While both most programs and most MUDs give a partial-line prompt, some
don't -- and displaying the newline wasted the last line of the output
window which was always empty.

They're removed by that point.

Required by POSIX 2001.

Not supposed to be missing on unices released in the last ~40 years.

Only Fruit OS X for now -- FreeBSD has trouble with autotools, and I want
to get rid of the latter anyway.

Ie, if there are "ass" and "assassin", the latter will now match.
