Hi,
With the #endif and data/sdata change, it compiles here again but still
doesn't work. qemu appears to spin forever, gdb shows:

Hi,
I tested qemu compiled with gcc 2.95.3 on PowerPC and it passes the regression
test. I think it is a glibc or compiler problem. Which version of gcc and glibc
do you use ?

Just tried 2.95.3 and it works beautifully, and it's a lot faster than
older version. Good job!
So 3.2.3 and 3.3-release definitely don't work.
