Each compilation state has its own symbols.  If you know what symbols
you need you can transfer them like this:

  addr = tcc_get_symbol(s1, "foo");
  tcc_add_symbol(s2, "foo", addr);

If you want to have just all symbols, look here:

It should work.  From tinycc/win32:
 $ build-tcc.bat
 $ gcc ../tests/libtcc_test.c -I libtcc -L libtcc -ltcc -o libtcc_test.exe
 $ .\libtcc_test
 Hello World!
 fib(32) = 2178309
 add(32, 64) = 96

You could try latest development ("mob") branch:
 http://repo.or.cz/w/tinycc.git?a=shortlog;h=refs/heads/mob
You can use git:
 $ git clone git://repo.or.cz/tinycc.git
 $ git checkout -b mob origin/mob
or download a snapshot.
