[Xen-devel] [Patch] ioemu-remote: fix gcc4 build problem (?)

[Andre Przywara <andre.przywara@xxxxxxx>]

Ian,

although I read that the gcc4 build problem should already be fixed, I 
cannot ack this for me: I just did
$ git clone http://xenbits.xensource.com/git-http/qemu-xen-unstable.git 
and "$ hg pull -u" in xen-staging and still configure stops with missing 
gcc3. In ioemu-remote "git log" says the latest patch was:
----------
commit 1ec7aa3263bc7fd78bcc40e4ceb2ca067a1a8687
Author: Ian Jackson <iwj@xxxxxxxxxxxxxxxxxxxxxxxx>
Date:   Mon Jul 14 13:46:28 2008 +0100
    qemu ioemu rendering fixes for palette handling (another dropped patch)
.....
----------

If a fix is already submitted, it would be nice if someone could point 
me how keep my tree up-to-date.
Anyway now my version of the patch:
AFAIK the qemu gcc3 build restriction does not apply to ioemu, in the 
old embedded tree "check_gcc" was set to "no" per default in 
tools/ioemu/configure. Either we do the same in the ioemu-remote tree or 
use the below patch to fix the shell test error (already in qemu since 
May 23rd: 
http://lists.gnu.org/archive/html/qemu-devel/2008-05/msg00875.html) and 
call configure with --disable-gcc-check (which is closer to the upstream 
qemu tree).

Andre.
