+Fix C compatibility issues in the configure script
+
+This is necessary to avoid incorrectly failing probes due to expected
+compiler errors.
+
+Include <stdlib.h> for the exit function, and <string.h> for the
+strdup function.
+
+Use fake prototypes to avoid implicit function declarations in the
+xine_* function probes.
