I think the issues you raise are in addition to make_host. make_host should just say "ms-windows" or "ms-dos" (_not_ the same) or "cygwin" or "gnu/linux" etc. This is enough to determine things like $EXEEXT etc. We could then make more feature variables, like posix etc., or maybe a system_features variable that is a list, which could be used to fine-tune the Makefile. (For knowing what shell is available one can simply use $SHELL, so I'm not sure anything else is needed.) And what about make_version? _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
