That usage would be correct (not -L/path/to/headers !).

Well, I can't say for sure where that stuff is coming from on your
system.  But, I would think the symbols are actually declared in the
header files (which are processed prior to compilation to object files).
However, later the linker tries to preferentially link to a library that
has *some* but not *all* of the symbols defined by the headers and hence
the mismatch.   Try grep'ing for those symbols in /usr/include and see
which files they turn up in (possibly term.h or termios.h).

Perhaps someone with more BSD experience can be of more help.
