[Qemu-devel] Gcc 4 building error

[Qemu-devel] Gcc 4 building error

[Alexander]

Hello. 
I have (GCC) 4.2.1, 
when i'm tried to build qemu from cvs, i've got such error: 

Code:

is this qemu bug, or gcc? 
is there any patches to avoid it?

Its known bug of gcc4. you should compile on gcc 3.
Please check the following qemu FAQ.
