[PD-dev] Pd 0.36 devel and IRIX

[Olaf Matthes]

Hi there,

attached are the files needed to compile the Pd 0.36 *developer* branch 
from CVS for SGI IRIX 6.5. I'm too lazy to learn how to check in my 
stuff (since I'm a "stupid windows user"*), so maybe someone could do me 
a favour and check these files in.

Changes to the original version are:

makefile.irix:

- compiles on IRIX 6.5 using GCC (n32 or o32 binaries)

t_main.c:

- small change to remove 'unresolved external symbol' error

sgi.c:

- using new audio API (al* instead of AL*)

- made -audiodev and -audioindev & -audiooutdev working, specifying no 
audio
  device (or -1) results in the default device selected in 'Audio Panel'
  being used

- added support for multiple audio devices: use -audiodev 1,3 -channels 2,8
  to open stereo AnalogIO and 8 channel ADAT-IO to get a total of 10 
channels

- made -r working, it now overwrites the sample rate setting in audio
  panel and defaults to 44100 Hz

- made -realtime (-rt) work: pd runs with a priority of 192,
  pd-watchdog with 250 and the pd-gui with 20 to overcome audio drops

- memory locking when in realtime mode

- added -listdev printout


Many thanks for checking it in! BTW, this is based on a checkout I did 
on Dec. 16th, just in case anything changed in t_main.c in the meantime.


best,
Olaf
