/* GCC always defines __STDC__.  HP C++ compilers don't define it.  This
   causes trouble when sys/stdsyms.h is included.  As a work around,
   we define __STDC_EXT__.  A similar situation exists with respect to
   the definition of __cplusplus.  We define _INCLUDE_LONGLONG
   to prevent nlist.h from defining __STDC_32_MODE__ (no longlong
   support).  We define __STDCPP__ to get certain system headers
   (notably assert.h) to assume standard preprocessor behavior in C++.  */
