* src/w32proc.c (sys_kill): Translate SIGTRAP signal into a call to 'DebugBreakProcess' to cause a breakpoint exception to occur in the specified process. On Windows versions prior to Windows XP that do not support 'DebugBreakProcess' return -1 and set errno to ENOTSUP (as opposed to EINVAL before this change). * src/w32proc.c: Add typedef for 'DebugBreakProcess' function pointer and global variable to track state of run-time dynamic linking of this function. * etc/NEWS: Add entry to document that 'signal-process' now supports SIGTRAP.
