From: Guohuai Shi <guohuai....@windriver.com>
Some of Windows error numbers have different value from Linux ones.
For example, ENOTEMPTY is defined to 39 in Linux, but is defined to
41 in Windows. So deleting a directory from a Linux guest on top
of QEMU from a Windows host complains:
# rmdir tmp
rmdir: 'tmp': Unknown error 41
This commit provides error number translation from Windows to Linux.
It can make Linux guest OS happy with the error number when running
on top of QEMU from a Windows host.
