shared libraries should not be distributed

[sds]

As explained in http://cvs.savannah.gnu.org/viewvc/*checkout*/ffcall/README?root=libffcall
There is absolutely no reason to build libffcall shared libraries.
Moreover, they are actually harmful.
In fact, the crash reported in https://bugs.launchpad.net/ubuntu/+source/ffcall/+bug/751112
is caused by the shared libraries: when clisp is build with libffcall shared libraries (i.e., "-lavcall -lcallback")
the test suite segfaults, but when clisp is built with libffcall static libraries (i.e., "/usr/bin/libavcall.a /usr/lib/libavcall.a")
everything works just fine (as explained in
https://bugs.launchpad.net/ubuntu/+source/ffcall/+bug/274951).

Let me repeat:

1. the package libffcall1 which only distributes libavcall.so and libcallback.so should be REMOVED.
There is no reason to distribute the shared libraries.

2. CLISP should be linked with libavcall.a and libcallback.a - statically.
otherwise it crashes in FFI callbacks.

3. libffcall1-dev should be kept, it works just fine; but it should NOT depend on libffcall1.

if you insist on using --enable-shared, you can just upgrade to the upstream cvs which now ignores --enable-shared
