I do -- I have a project which builds several slightly-customized versions, and I'd like to keep the generated objects around if possible.

So I just build one version, then "git cancel FOO" to the next version, and let the make rules take care of rebuilding what needs to be rebuilt.

("cancel" already does most of the job anyway, i.e. cleanup stuff which the build process might have changed that it shouldn't have.)

Cf. the last of the patches I've just mailed to the list.
