Windows does not seem to have this function either.
With your patch I was able to compile most of the targets from the current 
CVS tree (except arm), but at least i386-softmmu is broken.

It crashes immediately with the following error:

Starting program: c:\qemu-dist9/qemu.exe -L . -hda c:\qemu-img\wxp.q2 -boot 
c -localtime -m 512 -net nic,model=rtl8139 -net 
tap,ifname=TAP0 -kernel-kqemu

Program received signal SIGSEGV, Segmentation fault.
