This commit garbage collects the termio and sgtty support. GDB's terminal handling code still has support for the old termio and sgtty interfaces in addition to termios. However, I think it's pretty safe to assume that for a long, long time, Unix-like systems provide termios. GNU/Linux, Solaris, Cygwin, AIX, DJGPP, macOS and the BSDs all have had termios.h for many years. Looking around the web, I found discussions about FreeBSD folks trying to get rid of old sgtty.h a decade ago: https://lists.freebsd.org/pipermail/freebsd-hackers/2007-March/019983.html So I think support for termio and sgtty in GDB is just dead code that is never compiled anywhere and is just getting in the way. For example, serial_noflush_set_tty_state and the raw<->cooked concerns mentioned in inflow.c only exist because of sgtty (see hardwire_noflush_set_tty_state). Regtested on GNU/Linux. Confirmed that I can still build Solaris, DJGPP and AIX GDB and that the resulting GDBs still include the termios.h-guarded code. Confirmed mingw-w64 GDB still builds and skips the termios.h-guarded code. gdb/ChangeLog: 2017-11-06 Pedro Alves <palves@redhat.com> * Makefile.in (SER_HARDWIRE): Update comment.
