First they are renamed:
#define glDeleteFramebuffersEXT __aglDeleteFramebuffersEXT

then in extensions.c, in an obfuscated macro they are defined:

/* Define the GL API pointers.
 * Example:
 * ALLEGRO_BlendEquation_t __aglBlendEquation = NULL;
 */
#define AGL_API(type, name, args) ALLEGRO_##name##_t __agl##name = NULL;
#	include "allegro5/opengl/GLext/gl_ext_api.h"
#undef AGL_API
