Hi all
So I'm trying to set up a Pyston development environment
On make, it fails with
ninja: Entering directory `/home/greg/w/pyston/build/Debug'

So this is inside libunwind
At the revision that it's pinned to as a submodule in pyston

Oho, I bet this is architecture-dependent
These header files certainly have a lot of architecture-dependent logic, for sensible reasons
and I'm on x86_32

Hmm, I'm actually puzzled now why this doesn't break the same way on x86_64
but anyway, even if I fix this my real problem will soon become that I'm on x86_32
so I'll fix that

I never saw this error before but I know x86_32 bit is definitely not supported :-(
had you already found time to try a 64bit build? I think it should work on 12.04 because AFAIK travis ci is using this version.
