Having a user named 'root' in passwd is irrelevant. What matters is
whether you are logged in to Windows with a user account that has
Administrator privileges. Is that what you mean by "running the program
as root"?
To be clear, it doesn't matter at all what you name the user or what you
put in /etc/passwd or /etc/group, what matters is whether Windows
considers the user to have admin privileges, as the return value of
open("/dev/mem") is just a direct translation of the result of calling
the NT function to open \device\physicalmemory, so it's up to Windows
whether this fails or succeeds, not anything in Cygwin.
