make posix.mak is the way.

Please post a patch for that, and I'll merge it in.

Attached the patch (the pattern uses % instead of * and the 10.5/10.6 arguments are reversed on line 40).

There is an easy way to install the 10.5 SDK on a 10.7 machine: http://lunokhod.org/?p=269

Maybe that would be a viable solution to keep 10.5 support - of course assuming that it's really just the SDK.

You don't actually need the 10.5 SDK to create a 10.5-compatible binary, unless you're compiling for PowerPC. All you have to do is use the "-mmacosx-version-min=10.5" argument when invoking GCC and make sure you're not using any API not present on 10.5 (and if you're using one it'll be weak-linked and you have to check at runtime if it exists before using it). You can still use the 10.6 or 10.7 SDK, or not specify any SDK letting the compiler use the system-installed headers and libraries. I'm doing it with my apps, and it works great.
