Some release notes I just found seem to suggest it is
http://sourceware.org/binutils/docs-2.17/ld/WIN32.html :

This feature is enabled with the `--enable-auto-import' command-line
option, although it is enabled by default on cygwin/mingw. The
`--enable-auto-import' option itself now serves mainly to suppress any
warnings that are ordinarily emitted when linked objects trigger the
feature's use.

2.17 is from 2007, so it's been enabled by default at least since then.
