Shouldn't that be '-lboost_system'? Run 'info ld' and search for
'--dll-search-prefix': 'cyg-' is a typical default prefix that
the '-l' option should recognize without your specifying it.

Does this thread
  http://cygwin.com/ml/cygwin/2011-10/threads.html#00440
contain the answer? If this is a console application, does it have
an implementation of main()? Or if it's a windows GUI application,
is WinMain() implemented in some object file passed to the linker?
