There are some files in ftp.eecs.umich.edu's mirror of the source tree
that are 0-sized, when the same files are not 0-sized in
ftp.netbsd.org's tree.  All of the affected files are under
/BSD/NetBSD/NetBSD-current/src/gnu/usr.bin/gas/config:

tc-ns32k.[ch]
tc-sparc.[ch]
tc-tahoe.[ch]
tc-vax.[ch]
te-dpx2.h
te-generic.h

Gas won't build on *any* port without te-generic.h (which is how I
noticed the problem; I run i386) and some ports will have problems
building gas without the appropriate tc-*.[ch] files.

All FTP/sup mirrors should run 'sup -o' instead of 'sup' regularly to
prevent this sort of thing....

The following files are 0-length on *both* repositories:

tc-mips.[ch]
tc-rs6000.[ch]

Does NetBSD/pmax not use the version of gas that's in the tree?
