[Qemu-devel] Which compiler to use to compile current SVN

[Brad Campbell <brad@wasp.net.au>]

G'day all,

I can't get current SVN to compile at all here (same problem with regard to register spill other 
people are seeing). I applied Blue Swirls patches (as seen here 
http://lists.gnu.org/archive/html/qemu-devel/2008-03/msg00320.html) and cleaned up the rejects, but 
I just get stumped further on...

I'll download and compile a specific compiler if there is one guaranteed to compile cleanly (or even 
work at all). What compilers are the major developers using that actually function?
