alsa-lib with non-versioned symbols

[Takashi Iwai <tiwai@suse.de>]

Hi,

i found the build-problem of alsa-lib on my old machine.
the libtool on it is too old and doesn't support the additional linker
options.  thus -Wl,--version-script=xxxx option was not passed
correctly.  i guess this is also the case that Kai encountered.
(ld itself can handle versioned symbols well, btw.)

unfortunately it looks difficult to fix.  the old libtool cannot
handle such a case.  thus, now, the option is

- upgrade libtool

or

- build alsa-lib without versioned symbols.

i fixed a bug on cvs, so that alsa-lib can be built properly with the
option "--with-versioned=no".
even with this option, both old and new API coexist.  the new API
functions are defined with __ prefix as well as the
versioned-symbols.
then, perhaps, the second one is an easy solution.

i think that __ prefix and alias are not a perfect solution, too, but
we can remove such a workaround eventually when libasound goes to
so.3 at some time.
