I run the sloccount program on libc, gnumach, hurd, oskit-mach and mig.
Adding oskit would have added a real huge amount of code, too ;)

libc contains support for many platforms, one reason why it adds
substantially to the overall size.
gnumach is six times larger than oskit-mach in number of code lines.
But don't forget that oskit is larger than gnumach ;)

According to this, it takes about 50 person years to develop the Hurd.
So I would say we are within schedule ;)
