GCC in AIX

[Vardhan, Sundara (GE Infra, Energy)]

Hi Andrew

Did as you have adviced. Had to change config.in in gcc/libiberty. In
config.in

#ifndef __cplusplus
#define inline __inline
#endif

Changed that to
#ifdef __cplusplus
#define inline __inline
#endif

After this change it compiled fine. However, I have not yet investigated
the implications of this change overall.

Thanks much.

With Regards

Vardhan

Well, you know, if I were there I would have actually looked inside
./config.h" to see what xlc was complaining about.  It might be
interesting.

You could try that.  And if you find out that inline is being
incorrectly redefined, you could fix it.

Andrew.
