You're right; on the 1st April, I guess that makes me an April Fool :-)

On the other hand, it has raised a couple of questions.

1. At what point will there be a new release of the software?

Is there a target being worked towards? 

2. How do I compile my simple test program?

This used to be good enough:

gcc flags_test1.c -o flags_test1 qemu-0.9.1/arm-linux-user/libqemu.a \
   -I qemu-0.9.1 -DNEED_CPU_H -Iqemu-0.9.1/fpu -I qemu-0.9.1/arm-linux-user/ \
   -Wall qemu-0.9.1/osdep.c -I qemu-0.9.1/target-arm/ -D_XOPEN_SOURCE=600

But now libqemu.a seems to need a lot of features from other places that I
can't easily identify.  (Just osdep.c covered everything, before.)

I can understand the emulator needing wrapped malloc-like routines, but why
does the base emulator (which is what I thought the libqemu.a file
contained) need to know about mmap_lock?

I'm a little frustrated, and inclined to go back to using the 0.9.1. library
with my patch to continue, although there are presumably other improvements
to the development build.

Thanks,
Simon
