Thiemo,
I've attached both the semaphore and message queue patches to
this message since there is a dependency between them (message queue patch
must be applied on top of the semaphore patch).
This is updated to 6/01 cvs, and includes the additional part to
fix alpha the same as is done for the other archs. It also cleans up the
warnings in the new code areas.

It produces too many compiler warnings to be comfortable with, and breaks compilation of alpha-linux-user. I think alpha was actually added after I first created this patch, and I haven't been building it as it's not one of the archs I normally use. Note to self to do a build w/ everything turned on more often. The fix for it is to remove the same stuff as is done for a couple of the other archs. I'll clean it up, and take another look at the warning for this and the message queue patch, and resubmit. Stuart Stuart R.

[Qemu-devel] [PATCH] linux-user semaphore structure mapping
This is a refresh (vs 5/28 cvs) of a patch sent several weeks ago. This
patch implments the structure handling for the semaphore IPC related
structures used by semctl().
This was tested using LTP on an ARM target.
Were there any objections to this patch?
