I'd say "runs" - Bruno explained that 'dup' and 'dup2' are used in
auxiliary replacements from fchdir.c, and 'rewinddir' is only used in
a chroot+Linux corner case which won't happen on PSP (getcwd still
works in the general case).

AFAICS pspdev provides 'fnctl' with 'F_DUPFD' support, so indeed that
should be easy to add (in 'newlib/libc/sys/psp/libcglue.c'), thanks
for the tip!
