  21    causes trouble when sys/stdsyms.h is included.  As a work around,
  22    we define __STDC_EXT__.  A similar situation exists with respect to
  23    the definition of __cplusplus.  We define _INCLUDE_LONGLONG
  24    to prevent nlist.h from defining __STDC_32_MODE__ (no longlong
  25    support).  We define __STDCPP__ to get certain system headers
  26    (notably assert.h) to assume standard preprocessor behavior in C++.  */
