Cygwin has a struct, wincap, which indicates what Windows capabilities
are present.
This has a member, has_security, which is checked before any security
functions like OpenProcessToken
are used.
The struct is initialized in wincap.cc which calls GetVersionEx to
determine the version
of Windows being used, then copies a const version of the wincap struct
for that
Windows version onto the actual struct used. This has has_security set
to false for non-NT versions
of Windows.
So presumably setting the Wine version should avoid this... haven't
checked though,
just looked at the cygwin sources
