* readline/aclocal.m4: Use AC_TRY_LINK to check for mbstate_t.
* readline/complete.c (pwd.h): Guard with HAVE_PWD_H. (getpwent): Guard with HAVE_GETPWENT. (rl_username_completion_function): Guard use of getpwent. (endpwent): Likewise. * readline/config.h.in (HAVE_FCNTL): New macro. (HAVE_GETPWENT): Likewise. (HAVE_GETPWNAM): Likewise. (HAVE_GETPWUID): Likewise. (HAVE_KILL): Likewise. (HAVE_PWD_H): Likewise. * readline/configure: Regenerated. * readline/configure.in: Handle MinGW when cross compiling. Check for getpwnam, getpwent, getpwuid, kill, and pwd.h. * readline/display.c (rl_clear_screen): Treat Windows like DOS. (insert_some_chars): Likewise. (delete_chars): Likewise. * readline/shell.c (pwd.h): Guard with HAVE_PWD_H. (getpwuid): Guard with HAVE_GETPWUID. (sh_unset_nodelay_mode): Guard use of fnctl with HAVE_FNCTL_H. * readline/signals.c (rl_signal_handler): Don't use SIGALRM or SIGQUIT if not defined. Use "raise" if "kill" is not available. (rl_set_signals): Don't set handlers for SIGQUIT or SIGALRM if they are not defined. (rl_clear_signals): Likewise. * readline/tilde.c (pwd.h): Guard with HAVE_PWD_H. (getpwuid): Guard declaration with HAVE_GETPWUID. (getpwnam): Guard declaration with HAVE_GETPWNAM. (tilde_expand_word): Guard use of getpwnam with HAVE_GETPWNAM.
