All which stuff? If you are referring to OSS-lib stuff in soundcard.h, then I'm for it. Also giving an error with an ifdef OSSLIB like Arnd suggested would be nice, too. But maybe we need one more ifdef such as #ifdef OSSLIB #ifndef _SYS_SOUNDCARD_H #error ... #endif #endif thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
