Description
The .ninja_deps associated with a make instance running in ninja emulation mode uses an unsupported version of the ninja deps file format. emake will proceed as if the file was not present, and will write the deps file with the latest file version it supports when the make instance is terminated.
Reasons
The first several bytes of the .ninja_deps file should be a header indicating that the file is a ninja deps file and giving the version of the deps file format used. This message indicates that the header was present and was syntactically valid, but that the version indicated by the header was an unsupported version of the deps file format.
