[Ada] Fix exit status of GNAT.Expect.Close call on running process
gcc/ada/
* expect.c (__gnat_waitpid): Use macros WIFEXITED, WEXITSTATUS,
WIFSIGNALED, WTERMSIG, WIFSTOPPED, WSTOPSIG to get exit status
or signal that caused the child process to terminate/stop. Do
not process exit status in case of error in waitpid call.
* adaint.c (__gnat_kill): Use of GenerateConsoleCtrlEvent is
removed in Windows variant as it actually is not working and was
terminating the calling process. Set signal number into exit
code parameter of TerminateProcess to work the same like in
Linux.
