-@deftypefn Extension int pexecute (const char *@var{program}, char * const *@var{argv}, const char *@var{this_pname}, const char *@var{temp_base}, char **@var{errmsg_fmt}, char **@var{errmsg_arg}, int flags)
-
-Executes a program.
-
-@var{program} and @var{argv} are the arguments to
-@code{execv}/@code{execvp}.
-
-@var{this_pname} is name of the calling program (i.e., @code{argv[0]}).
-
-@var{temp_base} is the path name, sans suffix, of a temporary file to
-use if needed.  This is currently only needed for MS-DOS ports that
-don't use @code{go32} (do any still exist?).  Ports that don't need it
-can pass @code{NULL}.
-
-(@code{@var{flags} & PEXECUTE_SEARCH}) is non-zero if @env{PATH} should be searched
-(??? It's not clear that GCC passes this flag correctly).  (@code{@var{flags} &
-PEXECUTE_FIRST}) is nonzero for the first process in chain.
-(@code{@var{flags} & PEXECUTE_FIRST}) is nonzero for the last process
-in chain.  The first/last flags could be simplified to only mark the
-last of a chain of processes but that requires the caller to always
-mark the last one (and not give up early if some error occurs).
-It's more robust to require the caller to mark both ends of the chain.
-
-The result is the pid on systems like Unix where we
-@code{fork}/@code{exec} and on systems like WIN32 and OS/2 where we
-use @code{spawn}.  It is up to the caller to wait for the child.
-
-The result is the @code{WEXITSTATUS} on systems like MS-DOS where we
-@code{spawn} and wait for the child here.
-
-Upon failure, @var{errmsg_fmt} and @var{errmsg_arg} are set to the
-text of the error message with an optional argument (if not needed,
-@var{errmsg_arg} is set to @code{NULL}), and @minus{}1 is returned.
-@code{errno} is available to the caller to use.
-
-@end deftypefn
-
-@deftypefn Extension int pwait (int @var{pid}, int *@var{status}, int @var{flags})
-
-Waits for a program started by @code{pexecute} to finish.
-
-@var{pid} is the process id of the task to wait for. @var{status} is
-the `status' argument to wait. @var{flags} is currently unused (allows
-future enhancement without breaking upward compatibility).  Pass 0 for now.
-
-The result is the pid of the child reaped, or -1 for failure
-(@code{errno} says why).
-
-On systems that don't support waiting for a particular child, @var{pid} is
-ignored.  On systems like MS-DOS that don't really multitask @code{pwait}
-is just a mechanism to provide a consistent interface for the caller.
