C++ applications

You need to rebuild your binaries.
We've renamed QCC to be q++.
We've discontinued libcpp (the Dinkumware C++ library), and libc++ is now the default. Some work may be required to make everything play nicely.
You can use q++'s -Y option to select a specific C++ library to build with:

For this library: Use:

LLVM C++ library -Y_cxx

GNU C++ library -Y_gpp

There aren't any no-exceptions variants of the LLVM and GNU C++ libraries; add -fno-exceptions to CXXFLAGS.
With the Dinkum C++ library, if you included standard C headers using their nontraditional name (e.g., cstdio, cstring), the functions were put into the std namespace, but not into the global namespace. As an example, the following code wouldn't compile because printf() is in the std namespace, but not the global namespace:
```
#include <cstdio>
 
int main(void)
{
    printf("example\n");
    return 0;
}
```
However when you use the LLVM C++ library or the GNU C++ library, or with traditional C header names (e.g., stdio.h, string.h), functions end up in both the std and global namespace, so code like the above compiles without issue.
We support only C++11 and C++14 with libc++. Using older or new standards (C++98, C++03, C++1z (17)) may result in compilation errors. If these are absolutely required, it might be possible to do with some toolchain changes using libstdc++.

For this library:	Use:
LLVM C++ library	-Y_cxx
GNU C++ library	-Y_gpp
