This adds the name 'ad' to two unnamed unions in edid.h
and adjusts edid-parse.c for it. Nameless unions are not supported in
ancient gcc, which I happened to use on one of my ancient setups.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
