>Description:

I am not sure if 'bin' is a right category for this problem.

It occurs 'make buildworld' from freshly updated /usr/src for RELENG_5.
I took a look on it, and found that it's caused by -Wall in CWARNFLAGS.

Set WARNS=1 might be a temporary (and dirty?) fix for it.
However, somebody need to permanently fix it from /usr/src/usr.bin/lex/gen.c
