GH #91, PR #94 - Fix v1.27 regression where _open_tty() always passed O_NOCTTY, preventing make_slave_controlling_terminal() from acquiring a controlling terminal via the POSIX-standard open-without-O_NOCTTY mechanism (it was forced to fall through to an explicit TIOCSCTTY ioctl). _open_tty() now takes an optional noctty flag (default 1 for backward compatibility); make_slave_controlling_terminal() passes 0.
GH #92, PR #93 - Fix openpty() detection on Fedora 33-34 / glibc 2.32-2.33 where LTO flags (-flto=auto) caused the libc-only compile probe to falsely succeed, producing "undefined symbol: openpty" at runtime. Try -lutil before libc; harmless on systems where openpty lives in libc (glibc 2.34+, musl) and necessary where it doesn't.
Maintenance:
PR #90 - Address CPANTS kwalitee issues: add LICENSE, SECURITY.md, and CONTRIBUTING.md; add META `provides` for IO::Tty, IO::Pty, and IO::Tty::Constant; use --format=ustar in TARFLAGS to prevent PaxHeader entries in distribution tarballs.
Clean up MANIFEST.SKIP: add #!include_default so ExtUtils::Manifest's built-in skip list is in effect, drop five entries that duplicate those defaults, and add a ^\.claude/ rule.
