22 | /* GCC always defines __STDC__. HP C++ compilers don't define it. This |
23 | causes trouble when sys/stdsyms.h is included. As a work around, | |
24 | we define __STDC_EXT__. A similar situation exists with respect to | |
25 | the definition of __cplusplus. We define _INCLUDE_LONGLONG | |
26 | to prevent nlist.h from defining __STDC_32_MODE__ (no longlong | |
7dd7fb88 ZW |
27 | support). We define __STDCPP__ to get certain system headers |
28 | (notably assert.h) to assume standard preprocessor behavior in C++. */ | |
