Unsurprising.

What are you trying to do? Are you trying to build a git that does not know any of the built-in commands like "checkout", "commit", etc? Or do you still want a full-featured git, but because you know the code to perform "git foo" for any builtin command "foo" is contained in git executable itself, you want to "rm -f git-foo" from the filesystem?

The latter is a bad idea to begin with, as it will break older scripts that trust the promise that by having git --exec-path early on the $PATH older forms "git-foo" will always work.

If you really want to do so, the right way is not by mucking BUILT_INS to empty. I do not know how GfW is built, but if it uses our usual Makefile, find the place where it installs the git-foo forms of links after it installs the main git executable, and comment it out.

And no, it will *not* be a compilation option, as the resulting installation will break the age-old promise we made to script writers.

Good luck, and have fun.
