[Yann E. MORIN <yann.morin.1998@free.fr>]

Nicolas, All,

On 2015-02-11 15:06 +0100, Nicolas Serafini spake thusly:

I'm not sure I understand. Is that an known issue because of Buildroot,
or is that a known issue that also happens outside Buildroot?

I mean: is that problem caused by Buildroot?

Well, I'm not too fond of patching those headers.

I do not completely grok all the inter-relations between X, egl and all
the other stuff, so I'd prefer we do not have such hack, especially if
the answer to my question aboce is that the issue is not caused by
Buildroot.
