AIX stdio.h header includes code specific for C++ that looks like:
extern "C" {
#ifdef __cplusplus
#ifdef ferror
#undef ferror
inline int ferror(FILE * _p)
{
return ((_p)->_flag & _IOERR);
}
#endif /*ferror*/
which generates code that makes the AIX linker and loader rather upset
because the inline function is not mangled and conflicts with the C
library.
This fixincludes patch protects this code with an addition test for
IBMCPP (not that IBMCPP will use GCC include-fixed headers, but ....).
Okay?
Thanks, David
* inclhack.def (aix_stdio_inline): New fix.
