theora - Apr 2017 - impossible to link against libtheoraenc (missing symbol th_comment_query_count)

I've got a huge problem with libtheora. All is fine if I link only 
against libtheoradec but as soon as I try to link also against 
libtheoraenc everything breaks down:

libtheoraenc.so.1 dlerror: libtheoraenc.so.1: undefined symbol: 
th_comment_query_count.

I've checked with NM to see how the libraries depend on each other:

nm libtheoraenc.so.1  | grep th_comment_query_count
                  U th_comment_query_count
nm libtheoradec.so.1 | grep th_comment_query_count
0000000000010b20 T th_comment_query_count

All fine, so linking order should be "-ltheoraenc -ltheoradec" but
then
I get undefined symbol th_comment_query_count.

I even tried the wrong way "-ltheoradec -ltheoraenc" which obviously 
also gives undefined symbol th_comment_query_count.

How in gods name is one supposed to link against libtheoraenc? What has 
been fumbled up here that it is not possible to resolve this stupid 
symbol? It's a T symbol, not a t symbol, so why is there a link problem?

Just to avoid questions, that's the command line (stripped of 
unimportant blunder):
g++ -o ... -ltheoraenc -ltheoradec -lvorbisenc -lvorbisfile -lvorbis -logg
