[Qemu-devel] Can't compile on whacky 2.6/2.4 hybrid

[David Barrett]

To be clear, I'm not at all surprised this doesn't compile on my server. 
 I have a custom 2.6 kernel injected into a 2.4 distribution running a 
bunch of ancient libraries and -- *gasp* -- I'm having trouble 
compiling.  (As you might guess, this isn't by choice.)  I don't 
honestly expect to get this to work, but on the off chance that it's 
obvious to somebody, can you suggest any way to get past this compile error?

I configured it with:

        ./configure --disable-sdl --disable-gfx-check

Here's my GCC configuration:

Thanks for any suggestions you have!
