Just so we're clear...
Currently while I do have a sourceware account,
I'm not in the gcc group, so don't have commit access,

    sourceware$ id -a|grep gcc
    [Exit 1]

so someone else would have to commit my changes.
Or add me to the "gcc" group and I will do it.

Another recently-approved change may be in limbo for this reason:

    avoid memory overrun in a test leading to potential double-free
    * testsuite/test-expandargv.c (writeout_test): Fix off-by-one error:
    i.e., do copy the trailing NUL byte.
