buildworld broken after installworld

I tried to buildworld and installworld in this morning. After that,
buildworld broken like this:

[snip]
===> lib/libedit
cc -O -pipe -march=pentium4 -I. -I/usr/src/lib/libedit     -c editline.c

and I checked fcns.h:94.

> cat /usr/obj/usr/src/lib/libedit/fcns.h
