I can tell you what the problem is, but not how to fix it.  

When you try to create dblib.lib, the linker is missing the .obj files
that contain the "unresolved" symbols it's complaining about.  Those
symbols lie in the tds object files.  Provide the linker with all the
object files it needs, and you're done.  

On my system:

$ ls build/src/tds/*.o
build/src/tds/challenge.o               build/src/tds/md5.o
build/src/tds/config.o                  build/src/tds/mem.o
build/src/tds/convert.o                 build/src/tds/net.o
build/src/tds/data.o                    build/src/tds/numeric.o
build/src/tds/des.o                     build/src/tds/query.o
build/src/tds/getmac.o                  build/src/tds/read.o
build/src/tds/gssapi.o                  build/src/tds/tds_checks.o
build/src/tds/hmac_md5.o                build/src/tds/tdsstring.o
build/src/tds/iconv.o                   build/src/tds/threadsafe.o
build/src/tds/locale.o                  build/src/tds/token.o
build/src/tds/log.o                     build/src/tds/util.o
build/src/tds/login.o                   build/src/tds/vstrbuild.o
build/src/tds/md4.o                     build/src/tds/write.o

tds_prtype for example is in token.o:

$ for F in  build/src/tds/*.o; do nm $F | grep tds_prtype | grep T; if  [
$? = 0 ]; then echo $F; fi; done 
000043b4 T tds_prtype
build/src/tds/token.o

You can use dumpbin.exe to do something similar.  

It could be that you have something like tds.lib that lacks token.obj.  

HTH.
