And it still leads to bugs during exec, such as when running libtool: "libtool hangs indefinitely on windows when used in msys due to cmd.exe call bug" https://savannah.gnu.org/support/?110901 This confirms, once again, that MSYS2 cannot be recommended. As a development environment for native Windows program, I continue to recommend Cygwin. Bruno
