Casts are now written like types in variable declarations. file: [0f77351c40] check-in: [4af49a13c3] user: js, branch: trunk, size: 2678 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [80508f23b4] check-in: [44f45c2e35] user: js, branch: trunk, size: 2673 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [4eea8469d9] check-in: [cec0f072f8] user: js, branch: 0.8, size: 2665 [annotate] [blame] [check-ins using] [diff]

Now that Clang switched to use _Nullable and _Nonnull instead of
__nullable / __nonnull, there is no longer a conflict with glibc, which
means we can just define _Nullable / _Nonnull to nothing if they are not
understood by the compiler (which did not work with __nullable /
__nonnull due to this conflict).

This also defines _Null_unspecified to nothing if unavailable. file: [7a2761c9a2] check-in: [d526d938d7] user: js, branch: trunk, size: 2659 [annotate] [blame] [check-ins using] [diff]

Using __nonnull directly doesn't work on systems using glibc, as glibc
defines __nonnull as a parameterized define. While this does not fix the
problem of Clang introducing __nonnull even though it conflicts with
glibc, this at least means it's possible again to compile things with
versions of Clang that don't support __nonnull on systems with glibc. file: [8e9c5825f8] check-in: [b7097a67b6] user: js, branch: trunk, size: 2661 [annotate] [blame] [check-ins using] [diff]

This also removes "bool *stop" from some blocks where it does not make
sense. file: [42752e55c6] check-in: [e8473b9db8] user: js, branch: trunk, size: 2565 [annotate] [blame] [check-ins using] [diff]

We assume now that every object understands retain, release, etc. so
that we can weaken the type from OFObject* to id. This makes it
possible to use different root object classes. file: [1fcc11b4c5] check-in: [e2b06423e0] user: js, branch: trunk, size: 1430 [annotate] [blame] [check-ins using] [diff]
