empty value.

I did notice the
ptsname():
Since glibc 2.24:
_XOPEN_SOURCE >= 500
glibc 2.23 and earlier:
_XOPEN_SOURCE
But that is the same text that appears in grantpt.3 and unlockpt.3, and
they get included with just _XOPEN_SOURCE.
I also noticed it this morning when I sent my patch for grantpt.3, but I
ignored it assuming I probably misunderstood its meaning since it worked
with just _XOPEN_SOURCE.
Does this mean that my grantpt.3 patch is wrong?
And that #define _XOPEN_SOURCE in the synopsys of unlockpt.3 is also
wrong?
I should not use just #define _XOPEN_SOURCE without a value in my
programs if I want to use ptsname(3), grantpt(3), unlockpt(3)?
