How does this workaround look like? What is the replacement of
in pthread.h it is defined as=20
#define PTHREAD_CANCELED ((void *) -1)

Please checkout the latest sanei_thread, I've included this.

Oh, I remember this problem. Can you please enable the debug-messages of
sanei_thread: export SANE_DEBUG_SANEI_THREAD=3D20
The output of sanei_lm983x is not needed there.

I remember your pthread approach in spring this year, is it possible to c=
check  this (which I assume that it worked) with the current version?

Thanks for helping
