21 /* 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++. */
