May I suggest to change to for more easier checking?

#define LOCAL_SCAN_ABI_VERSION_MAJOR 1
#define LOCAL_SCAN_ABI_VERSION_MINOR 0
#define LOCAL_SCAN_ABI_VERSION \
LOCAL_SCAN_ABI_VERSION_MAJOR.LOCAL_SCAN_ABI_VERSION_MINOR

This allows easy compiletime-checking to make a patch work with different
ABIs.
