Thomas, All,
On 2015-08-04 20:00 +0200, Thomas Petazzoni spake thusly:
> Until recently, only the C++ bindings of libsigrok needed a recent
> compiler because they are written in C++11. However, now, libsigrok
> itself is written in C11, which is only available since gcc 4.7.
Here are a few autobuild failures for this: ;-)

With those added to the commit log;
Reviewed-by: "Yann E. MORIN" <yann.morin.1998 at free.fr>
Note that I have not even attempted to build it with a gcc-4.7 to
validate. This is only a review...
Regards,
Yann E. MORIN.
> So, this commit replaces the CodeSourcery-specific exclusions by a

>
> The sigrok-cli and pulseview packages, which select libsigrok, are
> also updated accordingly.
