Description
The .ninja_log associated with a make instance running in ninja emulation mode uses an unsupported version of the ninja log file format. emake will proceed as if the file was not present, and will write the log file with the latest file version it supports when the make instance is terminated.
Reasons
The first line of the .ninja_log file should be a string indicating that the file is a ninja log and giving the version of the log 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 log file format.
