I've just built binutils 2.41 on Cygwin with the patch applied and all
seems well.  Linking protobuf is within the measurement uncertainty of
the previous build.  The "objdump the gcc binaries" exercise is ever so
slightly slower than with the other 2.41 builds and that time is spent
in system, so it seems that there are indeed instances where an extra
fflush gets inserted.  No further findings so far, I'll install it and
do a full build of gcc again tomorrow.
