It should fix the build issue.
But QEMU is unreliable on OSX even when it gets built.
I tried to bisect but lost some time trying to find a revision that actually 
builds. I thought I updated more this month...

55f8d6ac3e03d2859393c281737f60c65dfc9ab3 definitely works ok.
Then there are some thread-related changes which I suspect have side effects.
The guest starts but stales for a while several times, at least with Haiku.
And the screen (SDL, couldn't try with vnc since the OSX client violates the 
RFB specs and QEMU doesn't like it) stays white for some time, then is only 
updated a few times.
Then the IDE driver fails to get DMA working, disables the DMA and eventually 
goes a bit further.
