   I'm in the process of trying to port Bash (the bourne again shell) from
   the gnu project to a 3b2 300 runing SYS V rel 3.1.  After about a week of
   serious hacking around I have the thinkg compiling, but it refuses
   to link due to the lack of 4 symbols.

      sigblock
      sigsetmask
      sys_siglist
      sigpause

   Does anyone know A) What theese routines do?  B) How to get around them?

These are system calls used in bash to implement job control on BSD
systems, except for sys_siglist which is an array of signal names.
Look at the "#ifdef SYSV...#else...#endif" sections in nojobs.c to see
the corresponding SYS V names.

(I installed bash yestreday on a Sun 3 running SunOS 4 with no problems.)

In the bash Makefile, if OS is defined as SYSV, and JOB_CONTROL is
undefined, and SIGLIST is defined as siglist.o, then none of the
symbols mentioned above should be required to link bash unless you've
hacked it to death.
