Oh, and, the call to CreateProcessAsUserW in cygwin1.dll is *old*, as in
"May 2008".  The former call to CreateProcessAsUserA is in Cygwin for
over 10 years.  However, just to be sure I installed the cygwin1-20100820
snapshot DLL on my W7 box and it works fine.  This is quite certainly a
local problem.  
Btw., after downloading cygwin1-20100820.dll.bz2 and bunzipping it, did
you make sure the executable bits are set (chmod +x cygwin1-20100820.dll)?
