I'm sorry but Android doesn't use the configure script.
The Android build system include the Android.mk in
the subfolders and build the targets defined in it directly.

I've tried to add cflag -DDOC_HIDDEN to Android.mk but
it generates more errors.

If change it to

#if !defined(DOC_HIDDEN) && !defined(NO_HWSYNC_WARNING)

and then define NO_HWSYNC_WARNING in Android.mk,
is it acceptable?
