if _mkfifo cannot be found, add "-DMKFIFO_MISSING" to SYSDEP_CFLAGS in
your machine's entry in machines.h.
If bash compiles, but hangs when executing a non-builtin, there is a
problem with the defines in your /usr/include/sys/wait.h. If you
don't have one, there is a problem in our defines. At any rate,
perhaps you have a partially POSIX system, instead of a fully
operational one. Try defining _POSIX_SOURCE just before the inclusion
of <sys/wait.h> in jobs.h, and then undefining it immediately after
the inclusion.
Finding out if your system has something (like setpgid, for example)
You can always do "nm -o /lib/*.a | grep setpgid". If an entry for
the function appears, you have it, and you might have to link with
that library by adding "#defined REQUIRED_LIBRARIES -lfoo" to the
entry in machines.h.
If you seem to be going around in circles, and they are related to
job control and posixness, try #undef HAVE_UNISTD_H in the entry for
your machine in machines.h. This can work by keeping unistd.h from
defining _POSIX_VERSION, which in turn prevents bash from assuming
full Posix semantics.
