Xen devel - Aug 2005 - Parallel builds with x86_64

I am trying to compile Xen on a SLES9 SP2 x86_64 Dell box.

When I do a "make -j4 world", I am getting the following error.

/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3/../../../../x86_64-suse-linux

But if I do a "make world" I don''t see this error. Any idea
why this is
happening?

I think there''s a concurrency bug in there somewhere - I''ve
been bitten on
x86_32 with it.

Building the kernels in parallel works fine and since this takes the majority 
of the time I usually do a parallel "make kernels" as a separate step.

Cheers,
Mark
