I made something similar for Amaya. I CVS tagged the parts of libwww that
Amaya uses and removed the examples, doc, and other libwww applications.

No. You'll need to patch your Makefile though. There's a line there
that checks if the .h files should be generated. It'll be better to remove
it.

No -D flags.

Yes. We do that in the Amaya Windows version.

It all depends on your application. If you have many libwww applications,
it makes sense to have DLLs rather than static libs. If compiling a big
libwww takes too much time, it may make more sense to have more mini
libwww's. There are other issues about how much of a library is loaded into
memory when the application is running (Unfortunately, I don't remember what's
the exact issue).

In the case of Amaya Windows, I made a new Makefile and we use a single .so.
You can try downloading a dsp file from the Amaya CVS repository (same one
as the libwww, under Amaya/Windows/), to get an idea.

So, in summary, it's possible to do what you have in mind. Bear in mind that
moving slightly from what's in the CVS repository will complicate a bit
your CVS updates. E.g., you'll have to remember to generate the .h files
each time, resolve conflicts in the Makefile, ...

Hope this helps,
