* movemail.c: Include <stdbool.h> and <signal.h>. (waitpid) [WINDOWSNT]: New macro. (wait) [WINDOWSNT]: Remove. (main, popmail, pop_retr, mbx_write, mbx_delimit_begin) (mbx_delimit_end): Use bool for boolean. (main): Simplify #if usage a bit. (main): Don't assume EOF == -1. Prefer 'return' to 'exit'. Don't possibly unlink lockname twice, as that's a race condition. Set SIGCHLD to SIG_DFL to work around SysV misfeature. Check for fork failure. Use waitpid, not wait, to avoid a race condition in the unlikely case where we start up with a child. (NOTOK, OK): Remove, in favor of plain boolean. (popmail, pop_retr): Don't get confused about errno, e.g., ferror need not set errno. (popmail): Use fclose (mbf), not close (fileno (mbf)), to also detect any stream-related errors (e.g., memory exhaustion). (pop_retr): Report pop errors separately, since caller now does errno reporting. (mbx_write, mbx_delimit_begin, mbx_delimit_end): Check < 0, not == EOF, as it's a bit faster and (in theory) pickier.

files that go in ${archlibdir}. At present, these are mostly utility
programs used by GNU Emacs.
