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. */
