Log:
Wed Nov 22 19:52:09 2006 Tim Janik <timj gtk org>
* bseladspa.cc: ported bseladspa.c to C++. use BIRNET_MAY_ALIAS to
work around strict aliasing warnings. load LADSPA modules with local
symbol bindings.
* bseladspa.h: fixed structure layout for C++.
* bsetype.h: use EXTERN_C in code generating macros, to account for
macro usage in C++.
