Hm, I can't see it in my libtool script (we are talking ltmain.sh right?). The
only time LTCFLAGS appears to be set anywhere in the net-snmp distribution is
in the configure script like
LTCFLAGS=${LTCFLAGS-"$CFLAGS"}
In fact,
bennizette@haruhi:~/dev/net-snmp-5.7$ grep -r 'stack-protector' .
<Changelog entries>
# -fstack-protector* stack protector flags for GCC
-O*|-flto*|-fwhopr*|-fuse-linker-plugin|-fstack-protector*)
bennizette@haruhi:~/dev/net-snmp-5.7$
For the sake of fiddling I removed the -fstack-protector clause from that
guard, no dice, also added an -fno-stack-protector one in case my
CFLAGS=-fno-stack-protector wasn't getting passed down to libtool. Also no good.
Cheers,
