I can confirm that the attached program works on cfarm111 (AIX 7.1)
and cfarm119 (AIX 7.3), though "man realpath" denies it on both
systems.

I also found leftover test files demonstrating that I checked this
same point on Apr 26 2024, so I'm not sure why that didn't turn up
in a mail list search.

#include <stdio.h>
#include <stdlib.h>

int
main(int argc, char **argv)
{
    char *pth = realpath(argv[1], NULL);

    if (pth)
    {
        printf("successfully resolved \"%s\" as \"%s\"\n",
               argv[1], pth);
        free(pth);
    }
    else
        perror("realpath");
    return 0;
}
