hello list:
I add some code to xen-3.1.0-src\xen\arch\x86\hvm\vmx\vmx.c to export some information when vmx_vmexit_handler() executed:

but when I compiled the xen,the error occured:
vmx.c:53:19: 错误:stdio.h:No such file or directory
vmx.c:54:20: 错误:stdlib.h:No such file or directory vmx.c:55:20: 错误:unistd.h:No such file or directory
How can I slove this problem?
Thanks.
