circular argument with configure in cygwin

[Mauricio Tavares]

      I am trying to compile krb5 under cygwin. So after untaring I
run configure:

$ ./configure
[...]
configure: error: Shared libraries are not yet supported on this platform.

$ ./configure --enable-static
[...]
configure: error: --enable-static must be specified with --disable-shared

$ ./configure --enable-static --disable-shared
[...]
configure: error: Shared libraries are not yet supported on this platform.

$ ./configure --disable-shared
[...]
configure: error: --enable-static must be specified with --disable-shared

Can anyone show what I am doing wrong here?
