Thank you very much for your details explanation, if possible, I shall
continue for them when I have time. At least I should know about whether
they have negative effect with my related patch which I will send to.
Under x86_64 linux, I guess, the reason of these failures are: during
compiling, I stop and modify gcc source code, then continue to compile,
so they may fail.
Under x86_64 mac, I did not touch anything during compiling, and compile
the 2 directories together:
- one for original latest gcc source code (master for 20140816).
- one for my modification based on the original latest gcc source code.
- they passed building, but for make check, they reported same issues:

For only sending my patch, may I bypass them, and then I shall try to
analyze them one by one in another time, next?
Welcome any ideas, suggestions or completions.
Thanks.
