make doesn't build

Hi

source cvs update'd some minutes ago (on amd64).
Building a new make fails:

cc  -O -DDEFSHELL_CUSTOM="/bin/sh" -DHAVE_SETENV=1 -DHAVE_STRDUP=1 
-DHAVE_STRERROR=1 -DHAVE_STRFTIME=1 -DHAVE_VSNPRINTF=1  -c 
/u/NetBSD/src/tools/make/../../usr.bin/make/var.c
/u/NetBSD/src/tools/make/../../usr.bin/make/var.c: In function 'Var_Set':
/u/NetBSD/src/tools/make/../../usr.bin/make/var.c:796: error: 'NIL' undeclared 
(first use in this function)
/u/NetBSD/src/tools/make/../../usr.bin/make/var.c:796: error: (Each undeclared 
identifier is reported only once
/u/NetBSD/src/tools/make/../../usr.bin/make/var.c:796: error: for each function 
it appears in.)
