Dear All,
I thought you might like to know the following:
Neither Qemu 0.7.2 nor 0.7.1 will compile under gcc 4.0.1, which is the
default under Mandrake 2006. It works fine with the older 3.3.6 though.
Here are the relevant bits of the output. I've cut all the irrelvant
bits, but I'm including the warnings in case they are useful. However,
the important bit is near the end. (I've separated the paragraph for
clarity.) The actual error is this:
/home/cvsp2/qemu-test/qemu-0.7.2/target-i386/ops_sse.h:574:
error: unable to find a register to spill in class 'GENERAL_REGS'
Hope that's useful.
Best wishes,
Richard

Gwenole has some gcc4 patches that work for gcc 4.0.3 on my system.
