kvm-18 compilation error

[Omar Khan]

hi,
   I am having trouble compiling kvm-18 on suse10.2. 'make' is giving the
following error:

You might try with gcc 3.4.6, which most people are using for qemu.  
Alternatively, ./configure --qemu-cc=gcc --disable-gcc-check, but then 
you lose the ability to run with the -no-kvm switch.

-- 
Do not meddle in the internals of kernels, for they are subtle and quick to panic.
