At the moment, I'm a bit short on time, but here is some stuff to help
with the problem.

sfarmer@hal [/usr/include]$ nm /usr/lib/libc.a | grep fdata
.fdatasync           T     619804
fdatasync            D     188972      12

This is in /usr/include/unistd.h:

        extern int      fdatasync(int);
        extern int      finfo(const char *, int, void *, int);
        extern int      ffinfo(int, int, void *, int);

  #endif /* ndef _KERNEL */

  #define _AES_OS_VERSION 1               /* OSF, AES version */

  #endif /* _ALL_SOURCE */

  #endif /* _H_UNISTD */

Included to the end of file as it shows the defs required/not allowed.
Full file attached.

Can I find out which unistd.h it looks in (there doesn't seem to be
any other on the machine, but one never knows)?
