All,
mq_timedreceive() returns ETIMEDOUT (110) on a timeout instead of -1 and errno set to
-ETIMEDOUT. This has been observed most recently on ppc32 and a year or so ago on a
little-endian arm board.
Any thoughts?
Thanks,Steven

What ppc32 board are you using?
Can you try following patch:
diff --git a/libc/sysdeps/linux/powerpc/sysdep.h
b/libc/sysdeps/linux/powerpc/sysdep.h
index c512c5a..9261174 100644

Similar to the ARM fix.

Yes that worked. Thanks.
This board is an mpc8347 based board. (e300c1)
I've also seen this issue recently on a ppc405 (virtex4)
