I too ran into the same problem on my SGI 3.2 system running the same
version of elm (Elm 2.3 PL0, of May 1, 1990).  I ended up defining the
symbol WEXITSTATUS() in config.h to make it work correctly.  My
definition was:

#define WEXITSTATUS(x)  ((x) & 0xFF)

and that made it work just fine.  Perhaps the configuration script should
ask about using WEXITSTATUS?
