# Sendfile:
#	-DUSE_INTERNAL_SENDFILE (less performance)
#		if you cannot use the sendfile syscall on your target platform with
#		64-bit file access.  Required for Unslung 5.5 on NSLU2.
#	-DUSE_INTERNAL_SENDFILE_MMAP (better performance)
#		Use along with -DUSE_INTERNAL_SENDFILE if your target platform supports
#		memory mapped files with 64-bit file access and you want to use it.
#		Won't work with >2GB files on Unslung 5.5 on NSLU2 due to bug in libc.
# DVD support:
#	-DUSE_DVDNAV
#		Use this to compile in support for libdvdnav usage (experimental)
