I assume that in this scenario, bsd.sys.mk is updated in your src/ but 
not on your host (/usr/share/mk/bsd.sys.mk).

However, gethost.nx (the program your build fails on) is built using 
host tools, so the bsd.sys.mk file from /usr/share/mk is taken which 
hasn't got the fix.

If you update it (e.g. quickly by 'cp share/mk/bsd.sys.mk /usr/share/mk) 
you should no longer need -DNO_WERROR for gcc44.
