Status of ptsname()

[Felipe Gasper]

Hello,

	libuv fails to compile on Cygwin; it chokes when trying to use ptsname(), which apparently Cygwin’s stdlib.h doesn’t define.

	`man ptsname` gives the impression that Cygwin implements this function. Since that doesn’t seem to be the case, should the man pages be updated to reflect reality?

	It’s worth noting that ptsname() is on this list as well: https://cygwin.com/cygwin-api/compatibility.html

	Thank you!

cheers,
