Hmm, sounds like Corinna's patch to set_file_pointers_for_exec: 
http://cygwin.com/ml/cygwin-cvs/2007-q2/msg00026.html

obeys POSIX but interferes with Windows.  It looks like when fd has O_APPEND 
set, that function will need to make a decision of whether the child being 
execed is non-cygwin, in which case it should seek to the end for the benefit 
of the child app.
