This fixes the above link error when building cygwin0.dll as part of a cross toolchain. The issue appears to be caused by this change in the mingw headers. It probably won't show up for anybody not building against the latest git version of mingw untill the next release. https://github.com/mirror/mingw-w64/commit/38410a I assume this function should still be added to autoload.cc, rather then modifying DLL_IMPORTS. I'll take a look at that.
