6.4 had a compile error:
```
scan.l:136:7: error: expected identifier or ‘(’ before ‘__extension__’
char *strndup(const char *s, size_t n);
^
```
This is caused by the standard library strndup() now living in string.h
and conflicting with another strndup() declared in scan.l. Version 6.9
fixes this.
This also removes the need for the boolean patch that we previously had.
From the changelog:
```
Version 0.7.76, 2015-08-06
+ XML output: line breaks and indents in between attributes for readability
+ Trace feature: XML trace update, only if compiled with trace feature
+ Amazon S3 support (REST API v2), CLI/DLL only and if compiled with
libcurl support
+ FFV1: improved slice analysis (currently activated only with trace
feature and for 1st frame)
x MXF: optimization of the parsing, reading a lot less data (e.g. can be
reduced from 1 GB to 10 MB with some UHD files)
x MXF: wrong frame count with files not having the video stream as the
first stream
x Dolby E in MPEG-TS: "SMPTE ST 302" information was accidentally removed
x MPEG-TS: avoid filling delay from file name, not applicable on MPEG-TS
x MXF: better handling of huge padding blocks, better handling of
descriptors without link to a TrackID
x IMX: streams claiming that they are IMX are actually pure MPEG Video,
probing both IMX and MPEG Video
```
Set QT_PLUGIN_PATH, QML_IMPORT_PATH, and QML2_IMPORT_PATH during build
so that Qt programs may easily be wrapped for use outside NixOS. The
paths are set appropriately for the dependencies of the package.
`nix-env -qaP -A pkgs.darwin`
pkgs.darwin.libutil:
Commented-out because the package definition doesn't exist. The source
doesn't even provide a Makefile...
pkgs.darwin.objc4_pure:
Commented-out because the package is broken and referencing unknown
applefetchsource and libc_old names. It doesn't seem to be used by any
other packages too.
