I'm saying that when cross-compiling, it's easy to produce binaries that are unusable on Windows because Guile is not run natively during the build, and so problems inherent to the Windows port are not revealed during the build. Multithreading is one such issue, quite a significant one. Unless I disable multithreading, I cannot build Guile natively, because every non-trivial Guile program crashes (I reported that years ago, but no one was able to explain why that happens or point me to a workaround). So if the above binaries include threads, I'm afraid they might not be very useful on Windows.
