[PATCH] AIX 5L shared vs static library logic

[David Edelsohn]

        The default, non-SVR4 (non-"runtime linking"-style) shared library
behavior of AIX uses a shared object placed in an archive file.  This
means that there is a filename conflict between a library archive of
object files and a shared library.  This normally is not a problem because
shared libraries should be used, if available, so the traditional archive
is not necessary.  One also may link statically with the shared library.

        When GNU Libtool builds a shared library on AIX, it should not
build a static library because that causes libtool to archive *both* the
shared object and the PIC object files in the archive, causing breakage.
There is logic in libtool.m4 to do this, but it only was testing for
target aix4* and was not updated to test for aix5* as well.

        The appended, simple patch corrects the oversight, making AIX 5L
behavior match AIX 4 behavior.  I would appreciate if someone would
approve it and commit it to the libtool repository.

Thanks, David

        * libtool.m4: Disable building static libraries if building shared
        libraries on AIX 5L.
