Hi all,

I've put "pd 0.26 patch 1" for linux on the web site,

to fix things for people whose audio drivers can't hack "GETISPACE"/
"GETOSPACE" ioctl calls.  In the patched version, if you invoke either
the "-frags" or "-fragsize" flag the audio buffer size is managed the
old fashioned way.  In this case, the "-audiobuf" flag is IGNORED; set
audio buffering with frags and fragsize only.

If you don't invoke "-frags*" you get the (much better) functionality
of 0.26.

The linux Pd distributions on my site are tested for redhat only;
Debian users may have to change some paths and remake.
