  You aren't running an executable on cygwin at all.  You are running a plain
old windows program.

  The standard response at this point is ....

 .... "what part of NO cygwin don't you get?"  :-)

  What you are writing is a plain old windows program.  The error message
comes from the windows C runtime library MSVCRT.  Whatever the source of the
problem is, it's nothing to do with cygwin and you'd probably be best off
getting advice from a windows/msvc/mingw programming list.
