In fact, looking at src/cairo-gl-private.h, we can see that GLchar is used in
functions related to shader loading. But the gl2.h file from sunxi-mali
defines prototypes using "char" where the official header from the Khronos
Group uses "GLchar". The gl2.h from Raspberry userland uses GLchar.

So the issue is with Sunxi Mali and has been fixed upstream:
