Issues building FreeBSD-current (head f9668e4)

[jake h]

Hey everyone,
I have been having some issues building FreeBSD-current from src, on
freebsd-13 (build 1300500). It appears to stem from several files compiling
with -Werror , despite my specification in make.conf of -Wno-error . As
these files then have warnings, the make kernel exits. A log of the error
is attached.
System info:
Current version: 13.0 - STABLE, build 1300500
make.conf: CFLAGS= -Wall -Wextra -Wno-error
Attempting to update to: 14-CURRENT (Git head f8668e4)

Thanks in advance for any help you can provide,
Jake
