Re: [Qemu-devel] Compile errors on Solaris for qemu 0.8.2

["Jonathan Kalbfeld" <jonathan.kalbfeld@gmail.com>]

I went ahead and made Leo's change and it built.  Also, I bit the
bullet and used the blastwave compiler.  However, I still get
segfaults trying to run sparc-test on qemu-system-sparc from my
sparc/solaris box.  Is this a known issue?  Also happens with mips.
