A General Question on Linking

[Malcolm Boekhoff]

If I have "../libsmutil/libsmutil.a" at the *end* of a command like:

    + gcc -o sendmail main.o alias.o arpadate.o bf_portable.o clock.o collect.o conf.o control.o convtime.o daemon.o deliver.o
domain.o envelope.o err.o headers.o macro.o map.o mci.o milter.o mime.o parseaddr.o queue.o readcf.o recipient.o savemail.o sfsasl.o
shmticklib.o srvrsmtp.o stab.o stats.o sysexits.o timers.o trace.o udb.o usersmtp.o util.o version.o ../libsmutil/libsmutil.a

does that mean that the default C library is not searched last?

I am asking, because the above command is producing this, but surely "sys_nerr" is defined in libc.a or one of the standard
libraries?:
