I, too, ran into this problem. It boils down to recent MinGW-w64 not
tolerating -Wl,--disable-auto-import:
https://sourceforge.net/p/mingw-w64/bugs/415

For now, I work around this locally by removing -Wl,--disable-auto-import from
src/template/win32. (Commit 1c9acd5 introduced our use of that flag for this
target.) Let's see how that MinGW-w64 bug progresses; if needed, we can have
"configure" check whether -Wl,--disable-auto-import works before using it.

Thanks,
