This is correct and expected behavior.

That's a problem with the ZIP format, which does not keep permissions.
Try "tar".

Cygwin does not assume any permissions. Neither does Windows. However,
Windows does have ACL inheritance rules that set everything to be
executable.
You can tell Cygwin to use default Windows permissions by temporarily
setting CYGWIN to nontsec, i.e., run
CYGWIN=nontsec unzip somefile.zip
This would not assign u+x, but rather a+x. There is no way that I know of
to get Cygwin to automatically assign only u+x.

BTW, the above would happen even if you didn't have the .exe extension.
Windows does not do special magic for .exe files -- it just makes
everything executable. A pretty annoying feature, if you ask me.
