I've successfully ported RCS to AIX Version 3 ... here are the diffs:

For rcslex.c:

  FILE *iop;
! const char *fmt;
  va_dcl
  /* Function: formatted output. Same as fprintf in stdio,
   * but aborts program on error

! fprintf(iop, fmt, va_alist)
  FILE *iop;

  va_dcl

For the Makefile:  (naturally some of the path names are locally defined)

That's it.

Check in /usr/lpp/bos for several excellent papers on the subject.
