Thanks for a quick response. Using only:
  -Wl,--major-subsystem-version,5,--minor-subsystem-version,10
 
gave the previous " .. is not a valid Win32 program..". Using 5,00, it loads okay.

Subsystem version 5.0? I've thought Win-XP was part of the NT family which 
started as subsystem ver. 4.0. Or is that required version of the console mode 
sub-system (3)?

Well, it's not so important. The reason I wanted to add this is that the
program communicates with a device-driver (OpenVPN's tap-drvr) that only 
works on Win-2K+. Off course it's better to check this at runtime.
