Hi, some observations:

- the configure.in script is broken for jack support. Also the gcc -mtune options is obviously not supported by all gcc versions/platforms (use -march instead). A fixed configure.in is attached (i can't check in at the moment, would someone please do for me?)

- with --enable-simd (on P4) the FFT examples like pvoc are silent, although the normal test tone patch is working as expected. Enabling/disabling FFTW support has no effect on that.

- the threaded soundfiler can't launch its thread when pd is started as "pd -rt" as a normal user.

- "pd -alsa" is always crashing (segmentation fault) when selecting devices in the user dialog.

best greetings, Thomas
