Heh! Thanks, yes. Plainly I'm out of practice with gcc patches.
Corrected version below, for completeness.

Remove the timestamped line from gengtype state file comment headers.
Gcc builds after r177358 include a file .../plugin/gtype.state as part of
their binary installation. The file contains a comment line that includes
the current date and time. Variations in the file contents due to only
changes in the timestamp can be an issue for build and packaging systems
that prefer or insist on binary compatibility.
This patch removes the comment line, to provide binary reproducibility for
any generated gtype.state files.
Tested for x86 and PowerPC, no bootstrap in both cases.
OK for google/integration? Also, OK for trunk?
