Thank you for your reply.

In sys/wait.h in the directory 'libgnu' in the build tree, I found 

*****************************
# ifdef __cplusplus
extern "C" {
# endif

/* Declarations of functions.  */

# ifdef __cplusplus
}
# endif

#else
/* Native Windows API.  */

# include <process.h>

# define waitpid(pid,statusp,options) _cwait (statusp, pid, WAIT_CHILD)

/* The following macros apply to an argument x, that is a status of a process,
   as returned by waitpid() or, equivalently, _cwait() or GetExitCodeProcess().
   This value is simply an 'int', not composed of bit fields.  */

/* When an unhandled fatal signal terminates a process, the exit code is 3.  */
# define WIFSIGNALED(x) ((x) == 3)
# define WIFEXITED(x) ((x) != 3)
# define WIFSTOPPED(x) 0

/* The signal that terminated a process is not known posthum.  */
# define WTERMSIG(x) SIGTERM

# define WEXITSTATUS(x) (x)

/* There are no core dumps.  */
# define WCOREDUMP(x) 0

#endif

# include <process.h>

# define waitpid(pid,statusp,options) _cwait (statusp, pid, WAIT_CHILD)

I attached sys/wait.h as a refrence.

In config.h, I found the following:

/* Define to 1 when the gnulib module gethostname should be tested. */
#define GNULIB_TEST_GETHOSTNAME 1

/* Define to 1 if you have the `gethostname' function. */
/* #undef HAVE_GETHOSTNAME */

/* Define to 1 if gethostname is declared even after undefining macros. */
/* #undef HAVE_RAW_DECL_GETHOSTNAME */

Any suggestions?
