I'd just say "Could not determine sources to transform".

----------------
As we talked about: until all transforms are smart enough to generate replacements only if they can make changes to all necessary files, we shouldn't transform all sources in the compilation database without an explicit -include. Otherwise none of the headers will transform and some (at least the use-auto_ptr transform) will produce broken code.

For now, exit with a message saying "Use -include to indicate which files of the compilation database to transform".
