Thank you, that worked.

This also affected s6-fdholder-transferdumpc, and, for the record, the
issue fixed by commit ebb6b00bf66828c5a2587dd2cd44f8810e01e00b (which
also worked) affected GNU libc-based operating systems as well, and
manifested as s6-mkfifodir not being able to create publically
accessible FIFO directories, so an s6 bugfix release seems in order
indeed.

It turns out GNU libc also has an unsigned gid_t

typedef __gid_t gid_t;

#endif

#define __U32_TYPE unsigned int

# error
#endif
#include <bits/typesizes.h> /* Defines __*_T_TYPE macros. */
//...
__STD_TYPE __GID_T_TYPE __gid_t; /* Type of group identifications. */

#define __GID_T_TYPE __U32_TYPE
