We shouldn't assume the GLchar is a valid typedef with all GL headers when declaring all the symbols in cogl-ext-functions.h to lookup. GLchar may not be avilable with gles1 for example so we were seeing build failures. The patch simply replaces occurrences of GLchar with char. Reviewed-by: Neil Roberts <neil@linux.intel.com>
