New Revision: 297299
URL: https://svnweb.freebsd.org/changeset/base/297299

Log:
  Compile libcxxrt as C++11, since it is only really used in combination
  with libc++, which is also C++11.  Also change one _Static_assert (which
  is really C11) back into static_assert, like upstream.
  
  This should help when compiling libcxxrt with newer versions of gcc,
  which refuse to recognize any form of static assertions, if not
  compiling for C++11 or higher.
  
  While here, add -nostdinc++ to CFLAGS, to prevent picking up any C++
  headers outside the source tree.
