[Qemu-devel] Re: supplement timegm function for Solaris in cutils.c |

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.
