Thanks for your patch. I had heard from Alexander you were working on
something, just hadn't seen what exactly.

Rather then linking everything into one big library, I think we should
clearly keep all subsystems seperate. Otherwise, we might end up with
the dependency hell we had (have?) in Samba3, with libbigballofmud and
the like. When installing libraries from Samba, these IMHO should be
seperate as well, for example, we could have:

- - libsmbclient (basically libcli)
- - libmsrpc
- - libtalloc
- - libldb
- - libtdb
- - libnet
- - libcom
- - libsocket_wrapper
- - libregistry
...

I'm currently trying to, in SVN:

- - Default all subsystems to being a 'MERGED_OBJ' / prelinked object.
If the OS supports it, we can do other stuff.
- - Make a distinction between subsystems that are a part of another
subsystem (NDR_RAW, etc).
- - All libs that are not part of another subsystem (those that have
MAJOR_VERSION and MINOR_VERSION set) will become shared libs if the OS
supports it. They'll be installed with Samba as well as their
specified headers.

Perhaps we can coordinate our efforts to improve the build system a bit?

Cheers,

Jelmer
