The distribution may choose not to support _XOPEN_CRYPT in the
case that the distribution has transitioned from glibc crypt to
libxcrypt.

With glibc fix 52a713fdd0a30e1bd79818e2e3c4ab44ddca1a94 for
CVE-2018-1000001 (Sourceware BZ #22679) the implementation in the
just released glibc 2.27 has been changed such that instead of
returning "(unreachable)" the implementation now returns ENOENT
as it would have if the current directory had been unlinked.
I see that in 2015 the quirk was documented in commit
a2ac97c78b, and this is no longer
true with glibc 2.27, but may continue to be true in other C libraries,
so I reference NOTES from the paragraph in the central text.

I am trying to fix a FIXME in the pthread_create.3 manpage.
It says info about default thread stack size should be put in
pthread_attr_setstacksize.3.
And pthread_attr_setstacksize.3 says "For details on the default
stack size of new threads, see pthread_create(3)".
So I list the default values for several architectures, starting
from glibc 2.12 (and still valid on current git glibc).

The manpage claimed that tsearch() returns a pointer to a data
item. This is incorrect; tsearch() returns a pointer to the
corresponding tree node, which can also be interpreted as a
pointer to a pointer to the data item.
Since this API is quite unintuitive, also add a clarifying
sentence.

As noted by Pradeep (and I tested also the code on OpenBSD):
The man page for fts library call states both the following:
short fts_pathlen; /* strlen(fts_path) */
fts_pathlen The length of the string referenced by fts_path
However, for the structures returned from fts_children() function,
fts_pathlen is strlen(fts_path) + strlen(fts_name), which contradicts
the man page statement. So I believe that there is either a bug in the
man page or the fts_children() library call.
The following program can be used for verification:
int main() {
struct passwd *pwd_entry = getpwuid(getuid());
char *paths[] = {pwd_entry->pw_dir, NULL};
FTS* fts = fts_open(paths, FTS_LOGICAL, NULL);
FTSENT* ftsent = fts_read(fts);
FTSENT* child = fts_children(fts, 0);
while (child != NULL) {
printf("\n %s %s %d %lu", child->fts_path, child->fts_name,
child->fts_pathlen, strlen(child->fts_path));
child = child->fts_link;
}
return 0;
}

Compile warning with glibc 2.25:
warning: In the GNU C Library, "makedev" is defined by
<sys/sysmacros.h>. For historical compatibility, it is
currently defined by <sys/types.h> as well, but we plan to
remove this soon. To use "makedev", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"makedev", you should undefine it after including
<sys/types.h>.
