I tried building a kernel with this line in my config file:

options         SETUIDSCRIPTS   # allow scripts to run set-uid

and got this as a result:

cc  -O2 -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -mno-fpu -I. -I../../../../arch -I../../../.. -DSUN4C -DSWAPPAGER -DVNODEPAGER -DDEVPAGER -DKTRACE -DSYSVMSG -DSYSVSEM -DSYSVSHM -DLKM -DSETUIDSCRIPTS -DCOMPAT_43 -DCOMPAT_10 -DCOMPAT_11 -DCOMPAT_SUNOS -DCOMPAT_SVR4 -DFFS -DQUOTA -DNFSSERVER -DNFSCLIENT -DKERNFS -DNULLFS -DMFS -DFDESC -DUMAPFS -DLFS -DPORTAL -DPROCFS -DCD9660 -DUNION -DFIFO -DINET -DPPP_BSDCOMP -DPPP_DEFLATE -DRASTERCONSOLE -D_KERNEL  -c ../../../../kern/exec_script.c

Stop.


I "fixed" this by removing "-Werror" from the makefile (cause I'm
lazy) but thought someone might want to properly fix it for the
impending release, or perhaps just for some point in the future.
I'd look into it more, but I'm already way behind on getting st(4)
in for review and a commit...  (Sorry Michael.)
