THat's not really strange.  It's the special handling of files with the
.exe suffix.  Under Cygwin 1.7, foo and foo.exe are treated as the same
file.  Already under older Cygwin versions, if you looked for a file
"foo", and there was only a file "foo.exe", the file was found, like
this:

  $ ls -l f*
  -rwxr-xr-x 1 corinna vinschen 19931 2009-11-19 09:15 foo.exe
  $ ls -l foo
  -rwxr-xr-x 1 corinna vinschen 19931 2009-11-19 09:15 foo

In Cygwin 1.7, it's even more treated as the same file.  If you
try to open "foo" for reading or writing, you will actually open
"foo.exe" if it exists.  You should not try to create a file foo
and a file foo.exe side by side in the same dir.
