I would have bet they are also accessible when doing the MXE build.
First they are in configure:
#ifndef WEXITSTATUS
# define WEXITSTATUS(stat_val) ((unsigned int) (stat_val) >> 8)
#endif
#ifndef WIFEXITED
# define WIFEXITED(stat_val) (((stat_val) & 255) == 0)
#endif
Another definition is in sys_wait:
liboctave/system/syswait.h:#define WIFEXITED(stat_val) (((stat_val) &
255) == 0) and also a definition in gnulib-hg/lib/sys_wait.in.h
