But this is not what the function AX_CHECK_PTYFUNCS actually does. It makes no attempt to include the required header. The two source files which call openpty() and login_tty() already contain the conditionals to include the required header. Remove the bogus m4 file to fix build with clang, which complains about calls to undeclared functions.
