Oh, and here's the snippet from the offending file
(core/sys/posix/sys/select.di):

------SNIP------
		private 
		{
			alias c_long __fd_mask;
			enum uint __NFDBITS = 8 * __fd_mask.sizeof;
			extern (D) auto __FDELT(int d);		// this is line 25

			extern (D) auto __FDMASK(int d);	// this is line 27

		}
------SNIP------

Looks like the problem is caused by the auto, perhaps?
