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.  */
