closure-size: chntpw broken, due to static libc being split out?

[deepfire]

Where does one read about the new rules of engagement in the closure-size?

It appears as if chntpw fails because a static variant of libc is no longer included:

gcc -DUSEOPENSSL -g -I. -I/usr/include -Wall -o chntpw chntpw.o ntreg.o edlib.o libsam.o -L/usr/lib64
gcc -static -DUSEOPENSSL -g -I. -I/usr/include -Wall -o chntpw.static chntpw.o ntreg.o edlib.o libsam.o -L/usr/lib64
/nix/store/2nk952dds3mrpz3spny7d2rzsl0b14fd-binutils-2.23.1-dev/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
Makefile:40: recipe for target 'chntpw.static' failed
make: *** [chntpw.static] Error 1
builder for ‘/nix/store/7x301a8m6i31j44qzdbkl1qzwj2q9nfb-chntpw-140201.drv’ failed with exit code 2

How do I feed chntpw a static libc?

When I do, I'm getting a linking error.

gcc -DUSEOPENSSL -g -I. -I/usr/include -Wall -o chntpw chntpw.o ntreg.o edlib.o libsam.o -L/usr/lib64
