@code{WTERMSIG}, @code{WEXITSTATUS}, @code{WNOHANG}, @code{WUNTRACED},

@code{WSTOPSIG} are not defined in @code{<stdlib.h>} (only in

Portability problems not fixed by Gnulib:

On Windows platforms (excluding Cygwin), the command processor used by the
|
|
@code{system} function is @file{cmd.exe}, not @file{/bin/sh}. Accordingly,
|
|
the rules for quoting shell arguments containing spaces, quote or other special
|
|
characters are different.
