It would help if coreutils would use libtool, but I don't know if upstream would be willing to consider that. In the meantime, since libstdbuf is just a module, the .so isn't a problem, and the build can be worked around with a bit of a hack: https://sourceforge.net/p/cygwin-ports/coreutils/ci/41db3dd6ed8d004e60b3005a9199e81306291b8c/ with the caveat that tests/misc/stdbuf.sh won't work in-tree. -- Yaakov
