    enums: don't write generated enum files to src-dir if unchanged · f9fa0d1b
    Ell authored
    When regenerating an enum file, don't copy it back to the source
    directory if it hasn't actually changed.  This allows using a read-
    only source directory where the enum header is newer than the
    generated file, as long as they're not really out of sync.
    
    OTOH, *do* touch the generated source-dir file even when unchanged,
    in order to avoid re-running its recipe on the next build, however,
    allow this to silently fail (which is harmless).
