string.h and std_cstring.h

[gp@qnx.com]

Thanks, Joe.  That could be it.  Our header has something like:

  #ifdef _cplusplus
  #define Const_ret const
  #else
  #define Const_ret
  #endif
..
..
  extern Const_ret char* strrchr(Const_ret char *, int);
..
..

So if I am remembering it right (I'm at home right now), then we get one or 
the other, but never both.  I am not sure about the inlines, but I will check.

I will work on it and let you all know.

Thanks again.
GP
