You can try to add "-e eth0 --privileged" to the command-line.
See the 'o.isr00t' stuff in mswin32/winfix.cc. Or disable the
__HrLoadAllImportsForDll() sillyness therein.

These results differ based on the position of
"-e eth0 --privileged" in the args list:

nmap -F -v -v -d -n
MS-DOS - FAIL - route_dst_generic: Failed to obtain system routes:
                getsysroutes_dnet: sysroutes_dnet_find_interfaces()

nmap -F -v -v -d -n -e eth0 --privileged
MS-DOS - FAIL - pcap_open_live(eth0, 256, 0, 2) FAILED.
                Reported error: Error opening adapter:
                The system cannot find the device specified. (20).
                Will wait 5 seconds then retry.
                ... Call to pcap_open_live() failed three times...

nmap -e eth0 --privileged -F -v -v -d -n

I bet there's a really simple explanation and I'm just not seeing the
wood for the trees.

That's a good clue. This may be a long shot, but please try this patch.
It defers calling win_init until option processing is finished,
including the options that have to wait to be processed until after the
whole command line has been seen.

The delayed option processing is a new thing added by Shinnok this
summer, which would explain why we haven't seen this error before.
