/* GCC always defines __STDC__. HP C++ compilers don't define it. This

| 22 |
|
|
causes trouble when sys/stdsyms.h is included. As a work around,
|
| 23 |
|
|
we define __STDC_EXT__. A similar situation exists with respect to
|
| 24 |
|
|
the definition of __cplusplus. We define _INCLUDE_LONGLONG
|
| 25 |
|
|
to prevent nlist.h from defining __STDC_32_MODE__ (no longlong
|
| 26 |
|
|
support). We define __STDCPP__ to get certain system headers
|
| 27 |
|
|
(notably assert.h) to assume standard preprocessor behavior in C++. */
