Preventing build breaks - using a pre-commit build

Question

What methods are available for preventing sloppy developers from breaking builds.
Are there any version control systems which have a system of preventing check-in of code which breaks the build.
Thanks

Answer 1

Microsoft TFS Build has something called "gated check-ins" which provides this, by performing a private check-in (called Shelving) which is promoted to a normal check-in if the build succeeds.

TeamCity has the concept of "delayed commit"

I can wholeheartedly recommend TeamCity!
