Thats why we use -pedantic.

Sorry, braced-groups are also invalid in ISO C, you said yourself above 
("and is a gcc-ism"). Therefore, a C++ implementation will not gain 
anything.

The fix is to add __extension__ to the offending statement system header, so 
that GCC will stop complaining. 

I really don't understand why this case is so much different to the other 
368 gcc-ism's in glibc headers.
