I tried to build Lucid and it successfully compiled.
But this problem is not reproducible on Lucid.
Then I tried to rebuild with Motif, but compilation failed with:

../lwlib/liblw.a(lwlib.o): In function `set_one_value':
../lwlib/lwlib.c:529: undefined reference to `lw_lucid_widget_p'

Then I used `make clean' in the lwlib directory,
and compilation succeeded.

And indeed, this problem is reproducible with a Motif build.

Please try running `emacs -Q -f tool-bar-mode' that disables tool-bar-mode
before it's displayed first time.
