Yes, but it doesn't compile the objects for non-libraries using libtool,
just like Jack explained.

Just don't, at least not outside of a *clean target.

No.

No.

That's why you should do it like this:

.pc.$(OBJEXT):
        ...

Then all of the above works, just like Jack wrote.

This is just done because one cannot teach traditional lex to produce
another output file.  The silliness really comes from the lex interface.
