This is kind of interesting from Stack Overflow
(http://stackoverflow.com/q/17775390):
<BEGIN SNIP>
This note in the gets manpage looks relevant:
ISO C11 removes the specification of gets() from the C language, and
since version 2.16, glibc header files don't expose the function
declaration if the _ISOC11_SOURCE feature test macro is defined.
Probably should be:
#if !_ISOC11_SOURCE
using ::gets;
#endif

Title:
Clang 3.6 cannot compile program with -std=c++14
Status in llvm-toolchain-3.6 package in Ubuntu:
New
Bug description:
Clang 3.6 provided by Ubuntu claims to support C++14. -std=c++14 is
not rejected by the compiler during feature testing.
Attempting to compile a test program:
$ cat test.cxx
#include <string>
int main(int argc, char* argv[])
{
return 0;
}
Results in the following:
$ clang++ -std=c++14 test.cxx -o test.exe
