With a just-updated -current tree, I get

% sudo make distclean
[..]
clean ===> usr.bin/vacation
rm -f vacation.o  vacation.ln
rm -f a.out [Ee]rrs mklog core *.core .gdbinit vacation
clean ===> usr.bin/vgrind
make: Unclosed variable specification for CC
Segmentation fault - core dumped
*** Error code 139

Stop.
make: stopped in /home/users/mjl/netbsd/src/usr.bin
*** Error code 1


  I must admit this is the weirdest thing I've ever seen for a
distclean -- is my tree broken in some strange way?
