This cannot yet extract a file from the archive if the file spans
multiple parts. However, for a multipart archive with multiple files,
all files that only span a single part can be extracted. file: [cd5774f862] check-in: [630ea6bc5a] user: js, branch: trunk, size: 1211 [annotate] [blame] [check-ins using] [diff]

This matches Apple's style. file: [f1b3349a83] check-in: [6b77a5dd8b] user: js, branch: trunk, size: 932 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [aa6cbb3cc6] check-in: [4af49a13c3] user: js, branch: trunk, size: 883 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [94e173a584] check-in: [44f45c2e35] user: js, branch: trunk, size: 882 [annotate] [blame] [check-ins using] [diff]

This existed before, but was private.

Additionally, ofzip -lvvv now also shows the general purpose bit flag. file: [1c2a99ad72] check-in: [41e83e895c] user: js, branch: trunk, size: 877 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [1815b3651f] check-in: [cec0f072f8] user: js, branch: 0.8, size: 909 [annotate] [blame] [check-ins using] [diff]

Now that we can require GCC >= 4.6, we no longer need to fall back to
using a category on old compilers. file: [90b610f3ba] check-in: [2aca549d60] user: js, branch: trunk, size: 929 [annotate] [blame] [check-ins using] [diff]

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: [bc7d037fee] check-in: [48980f2297] user: js, branch: trunk, size: 948 [annotate] [blame] [check-ins using] [diff]

Every OFSeekableStream can be used now. file: [d8d4d53628] check-in: [aa1bb213e0] user: js, branch: trunk, size: 857 [annotate] [blame] [check-ins using] [diff]

This means that OFObject.h imports macros.h now, making it unnecessary
to manually import macros.h in almost every file. And while at it, also
import autorelease.h in OFObject.h, so that this doesn't need to be
manually imported in almost every file as well. file: [a6d0709e96] check-in: [13ee56edf3] user: js, branch: trunk, size: 845 [annotate] [blame] [check-ins using] [diff]
