Forgot to add 2017, even though I already did quite some changes in

This increases the required GCC version from 4.0 to 4.6 (exception:
Apple GCC, which already supports this with >= 4.0 starting with OS X
10.5). Since even GCC 4.6 is really old by now, there is no point in
still supporting something even older and making the code ugly because
of that. While some hardware and OS support was dropped from GCC 4.6
compared to GCC 4.0, there is nothing in there that would be an
interesting target with the exception of BeOS maybe - but a port to BeOS
can also be achieved using the Haiku support. The other dropped OSes are
mostly old versions of OSes while newer ones are still being supported
(and those newer versions of those OSes still support the same
hardware). file: [d0606515a9] check-in: [48980f2297] user: js, branch: trunk, size: 1280 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [00c1a07208] check-in: [c5ef582958] user: js, branch: trunk, size: 1215 [annotate] [blame] [check-ins using] [diff]

It is still implemented by all classes implementing OFCollection so far,
but new classes are not required to implement it anymore.

This is required to add OFCountedSet later, which can't support it. file: [5cef34a803] check-in: [8ff55bf218] user: js, branch: trunk, size: 1184 [annotate] [blame] [check-ins using] [diff]
