This could be a bad installation of the build tools or a bug in Apple's headers themselves. You could try grepping /usr/include for the definition of __DARWIN_ALIAS_STARTING to see where that is and seeing if including the file where it lives near the top on includes.h fixes it. (I don't have a High Sierra host, so can't help directly - sorry) -d _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
