hi guenter wie geht's?, all, thx for the feedback

I've just did make clean, patched, and now compiling spits something I
can't figure out:
...........................................................................
cc -g -O2 -DPD  -Wall -W -Wstrict-prototypes -Wno-unused
-Wno-parentheses -Wno-switch -O6 -funroll-loops -fomit-frame-pointer
-DDL_OPEN -DPA_USE_OSS -DPA_LITTLE_ENDIAN -DUNIX -DUNISTD
-DUSEAPI_OSS         -I../portaudio/pa_common -I../portaudio/pablio
-I../portaudio/portmidi-macosx   -fno-strict-aliasing -DPA_USE_ALSA
-DUSEAPI_ALSA -DUSEAPI_JACK -DINSTALL_PREFIX=\"/usr/local\" -I. -c
-o ../obj/s_inter.o s_inter.c 
s_inter.c: In function `sys_set_priority':
s_inter.c:272: error: storage size of 'mlock_limit' isn't known
s_inter.c:275: warning: implicit declaration of function `setrlimit'
s_inter.c:275: error: `RLIMIT_MEMLOCK' undeclared (first use in this
function)
s_inter.c:275: error: (Each undeclared identifier is reported only once
s_inter.c:275: error: for each function it appears in.)
make: *** [s_inter.o] Error 1
...........................................................................

something missing?

btw, sounds sexy that about kernel 2.6.12 fixing some low latency stuff,
can anyone confirm that more closer?

danke,
hasta luego,

PD: I insist in the fact about setting default "reply to:" to this ML posts as: _this list_
even if mailman strongly recommends to "original sender". but I think this forces an off-list
exchange pulling out of it some mails unless the responder figures out he wants to keep it "public"
and fixed the "To: " field to this list... no¿
