Add more C++11 highlighting

[jwakely]

• __cplusplus macro
• thread_local keyword
• <atomic> macros
• raw strings

[mattn]

Thank you. It seems ok to me. @osyo-manga @usagi How do you think?

I prefer separate them by if !exists("cpp_no_cpp11").

I think about adbefa2 c8a6c82 bc54412 , there are no problems.

But, I have a one question for ecc8719 .

These two keywords are no problems:

• "ATOMIC_FLAG_INIT" is in the C++11 spec. 29.7 .
• "ATOMIC_VAR_INIT" is in the C++11 spec. 29.6.5 .

But, the other keywords does not exist at least in the C++11 spec(ref: N3337).

• "ATOMIC_BOOL_IS_LOCK_FREE"
• "ATOMIC_CHAR_IS_LOCK_FREE"
• "ATOMIC_CHAR16_T_IS_LOCK_FREE"
• "ATOMIC_CHAR32_T_IS_LOCK_FREE"
• "ATOMIC_WCHAR_T_IS_LOCK_FREE"
• "ATOMIC_SHORT_IS_LOCK_FREE"
• "ATOMIC_INT_IS_LOCK_FREE"
• "ATOMIC_LONG_IS_LOCK_FREE"
• "ATOMIC_LLONG_IS_LOCK_FREE"
• "ATOMIC_POINTER_IS_LOCK_FREE"

These keywords are unspecified in the C++11. And, the spec 29.4 defined:

29.4 Lock-free property
#define ATOMIC_BOOL_LOCK_FREE unspecified
#define ATOMIC_CHAR_LOCK_FREE unspecified
#define ATOMIC_CHAR16_T_LOCK_FREE unspecified
#define ATOMIC_CHAR32_T_LOCK_FREE unspecified
#define ATOMIC_WCHAR_T_LOCK_FREE unspecified
#define ATOMIC_SHORT_LOCK_FREE unspecified
#define ATOMIC_INT_LOCK_FREE unspecified
#define ATOMIC_LONG_LOCK_FREE unspecified
#define ATOMIC_LLONG_LOCK_FREE unspecified
#define ATOMIC_POINTER_LOCK_FREE unspecified

And, these unspecified keywords has slightly different (ex.: "ATOMIC_BOOS_IS_LOCK_FREE" in the patch vs. "ATOMIC_BOOL_LOCK_FREE" in the spec.).

Do you know the source of these keywords in the patch?

I think good idea for the @mattn 's proposal to separate the files.

Oops, those were just spelling mistakes while typing them in. I've pushed a corrected version.

I don't understand @mattn's suggestion.

[usagi]

@jwakely It's okay. Thanks for your fix and patches.
@mattn I think these patches has no problems.

[osyo-manga]

Thank you patches :)
I think it's okay.

[mattn]

@usagi @osyo-manga Thank to your reviews.

@jwakely Ok, I'll merge it

[mattn]

Thank you all. I merged it.

[osyo-manga]

Thank you @mattn :)
