Well, there is this piece of code (in a context where signo == SIGCHLD): #if (defined WINDOWSNT \ || (defined USG && !defined GNU_LINUX \ && !(defined HPUX && defined WNOHANG))) #if defined (USG) && ! defined (POSIX_SIGNALS) signal (signo, sigchld_handler); #endif But... if MS-Windows does not support SIGCHLD (or SIGCLD), how does emacs detect process termination on MS-Windows?? -- Kim F.
