Appveyor glbinding incompatible with WL code

[hessenfarmer]

MSYS has upgraded the glbinding Version found by pacman on Appveyor to 3.0.2.1 which seems to have issues with the WL code. (was 2.1.4 previously whic just ran fine)

Short term solution could be to add an instruction to downgrade glbinding packet or use glew instead.

In the Long term the Problem has to be analyzed and fixed in the code imo.

ok I digged a little through the glbinding documentation.

made some changes to src/graphic/gl/initialize.cc and added the new headers to src/graphic/gl/system_headers.h

if it compiles I'll add the files as attachment

at least the changes compiled with my msys2 environment although I now have a final linking errror with icu but that might be unrelated. Here are my changes.

Thanks for looking in to this. Is there a reason that you're creating attachments instead of a branch?

[hessenfarmer (stephan-lutz)]

Mainly because I did my trials within an existing branch and had no time to properly branch one for this issue. It doesn't work at the moment either cause it has linking errors when finally linking the exe. The errors are related to the new aux namespace. But as I am afk from my dev machine I can't look into this until sunday. Probably it is recommendable to activate the old error handling again and delete the line with the aux:: function

The branch with the downgrade solution seems to work for the Moment being.

I found a possible solution for glbinding in this Project

I will test this tonight

We should also detect the Boost version properly rather than downgrading it on Appveyor. Let's get the dirty hack in first though to make sure we get it running again ASAP.
