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
|
|
27 support). We define __STDCPP__ to get certain system headers
|
|
28 (notably assert.h) to assume standard preprocessor behavior in C++. */
