@itemize
@item
The macros @code{WIFSIGNALED}, @code{WIFEXITED}, @code{WIFSTOPPED},
@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:
@itemize
@item
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.
