About enable-thumb, I'll give a try without (won't be able to test it on Windows, only have a phone arm device for now). About armv8, there is actually a ./lib/arm64 in the windows 10 dev kit, but no public compiler for this atm. I'll keep you posted if I get any news on that (and would be glad to help target this architecture on Windows 10). >> I also found some strange linking issues when building with >> disable-optimizations and / or as static libs.
