   I do not have rgrep; but I did do a grep on /usr/include and /usr/include/sys

# grep -E "DINFINITY|DQNAN" *
float.h:#define DINFINITY _DBLINF
float.h:        extern  unsigned   int DQNAN[2];
float.h:#define DBL_QNAN        (*((double *) (DQNAN)))
math.h:#define DINFINITY _DBLINF

   AIX is supposed to be compliant with the latest OSF specifications!
If you like you can check out the link below to get more information
about AIX compatability/compliance with UNIX standards.

   I did a grep on /usr/include and /usr/include/sys

# grep hstrerror *
netdb.h:const char      *hstrerror();
netdb.h:const char *    hstrerror(int);

   Hope this information is what you requested.
