Agreed. Using git or mercurial would get around this. I worked for nearly a decade on cross-platform code that followed a similar methodology.

Our rule was the code most compile w/o warnings on 3 dissimilar platforms before you could commit it. We were able to do this easily because we had network-mounted home directories, so when you logged into another machine, our development tree was automatically mounted. This made it easy to compile without checking in, then checking out.
