Presumably you meant "tar implementations" and not "make implementations"? But this is already the case, as the existing code uses the -o option, which is specific to GNU tar (the -o option has a different meaning with traditional tar, and traditional tar rejects -o when creating archives). > 2.

True: any such patch along these lines would have to configure this, depending on whether "tar" supported the option in question. Come to think of it, while you're at it you could also see whether -o is supported, so that the makefile ports to non-GNU tar implementations. > 3. The POSIX format is young Quite true. Few implementations support the POSIX 1003.1-2001 format. > Forcing the ustar format might be a possibility (is it?), if > that can be done portably (that probably involves a configure > check). Yes, I think this is the best approach: that is, use --format=ustar if available, then -o if that works, otherwise don't use anything. > Another idea is to arrange the dist rules so users have > a way to override the tar options. That also might be helpful, though I think not as useful; most users won't want to futz with this.
