So I think I've made a little progress here. I still don't have a 
solution, but I can now reproduce the problem.

The problem is triggered by default group ACLs on the working copy 
directory. When I run as a local administrator, a 
"default:group:Administrators:rwx" ACL will cause the ".exe" extension 
to be appended, while "d:g:Administrators:---" will avoid the problem. I 
see similar results for a non-admin user and the "Users" group.

I was running the script in a directory under /tmp, which doesn't have 
these default ACLs.

$ getfacl /tmp
# file: /tmp
# owner: drothe
# group: None
user::rwx
group::rwx
mask:rwx
other:rwx
default:user::rwx
default:group::rwx
default:other:rwx

But, if I run the script in a new directory which has the default ACLs, 
the problem appears.
$ mkdir /cygdrive/c/svn-tst
$ getfacl /cygdrive/c/svn-tst
# file: /c/svn-tst
# owner: drothe
# group: None
user::rwx
group::r-x
group:SYSTEM:rwx
group:Administrators:rwx
group:Users:rwx
mask:rwx
other:r-x
default:user::rwx
default:group::r-x
default:group:SYSTEM:rwx
default:group:Administrators:rwx     <<---- triggers problem
default:group:Users:rwx
default:mask:rwx
default:other:r-x

I've attached another reproduction script that sets the default ACL for 
each group to 0 on the working copy before doing the final checkout. 
This avoids the problem for me. Please let me know what you find.
