I noticed when looking through the source to pulseaudio 5.0 as aquired from debain that in file: src/module-simple-protocol-unix-symdef.h There are the following ifdef foo lines: 0 #ifndef foomodulesimpleprotocolunixsymdeffoo 1 #define foomodulesimpleprotocolunixsymdeffoo Is this intentional or are these a leftover from some kind of test?
