| 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++. |
| We define _XOPEN_SOURCE_EXTENDED when we define _HPUX_SOURCE to avoid |
| non standard hpux variants in _INCLUDE_XOPEN_SOURCE_EXTENDED. */ |
