8226242 : Diagnostic output for posix_spawn failure

[Thomas Stüfe]

Hi Roger,

thanks for taking care of this!

I think WIFSIGNALED is just a bool though; to get the terminating signal,
you need to use WTERMSIG. Strictly speaking, WEXISTSTATUS is only valid if
WIFEXITED!=0 and WTERMSIG only if WIFSIGNALLED!=0; I think they are
undefined otherwise.

Cheers, Thoams
