I noticed that readdir_r() does not have a prototype.
It should be in dirent.h. I am happy to add it to
the RTEMS dirent.h but there are other versions of
this file and
I can drop the prototype in those at the same time.
And ... Linux man page shows these guards. What should
they be on newlib?
_POSIX_C_SOURCE >= 1 || _XOPEN_SOURCE || _BSD_SOURCE ||
_SVID_SOURCE || _POSIX_SOURCE
It probably is not worth bothering with a guard.
dirent.h is not in the C standard, so there is no gate needed based on
it. (Someone could say that with your sample gate that it would be skipped with
STRICT_ANSI, but from that point of view, dirent.h should not even be included.)
POSIX says is was added in issue 2, which is so ancient that it seems
unreasonable to add something now to avoid it for someone trying to use issue
1. (I think that the guard would probably be _POSIX_C_SOURCE >= 199209 to be
for issue 2, assuming that sys/cdefs.h has been included before the check.) I
don't know why GLIBC's test is for 1, instead of 2.
