20/* GCC always defines __STDC__.  HP C++ compilers don't define it.  This
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++.
27   We define _XOPEN_SOURCE_EXTENDED when we define _HPUX_SOURCE to avoid
28   non standard hpux variants in _INCLUDE_XOPEN_SOURCE_EXTENDED.  */
