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>

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