No, this is my preferred option at this point.  SYS_INCLUDE=symlinks
is totally a second-class citizen at this point, and I don't really care
enough about it do want to bother making it work 100%.  If it can't be
made to work properly, then IMO is should just go the way of the dodo.

This is not a good option, because it could have the side-effect if
inadvertently zapping locally-modified source code files.

Extra complexity for what is obviously a corner case.  Not so good :-)

I agree with your assessment that (d) is not a reasonable option.
