Not necessarily.  To draw that conclusion, you would want to compare the
implementation of 'cp' compiled natively ('gcc -mno-cygwin' for example)
with Cygwin's and your little program.  Only if the natively compiled
version performed much closer to your program using CopyFile() could you
conclude that Cygwin is to blame.
