I inspected the release archives of gcc, binutils, glibc, libmpfr,
libgmp and libmpc and ascertained their release dates, either from the
archive date or in the cases where the archive date was wrong, from the
files inside the archive.

Now, I may be wrong, but it seems to me when a new GCC is being
released, it will be compiled for sure with the most recently published
glibc, libmpfr, libgmp and libmpc.  Similarly, it will be created with
the most recently release binutils.

These versions then I thought would be the "appropriate" versions, for a
given GCC.

That is a good question.

The library itself does not use even a freestanding implementation; it
compiles on a bare C compiler.

However, the benchmark app also benchmarks normal locking data
structures, as provided by the OS.  For Linux, all the usual suspects.
I assume - but I do not *actually* know, now I think about it to answer
the question - that these will depend, directly or indirectly, upon glibc.
