I'm trying to make the WebKit build reproducible, and one problem that I've found is that the CSSPropertyNames.cpp file generated by makeprop.pl is different in each build. The reason is the way makeprop.pl iterates over the contents of hashes, which by definition are not guaranteed to have a stable order in Perl. Fortunately this is easy to solve, I'm uploading a patch.
