trying to solve some missing symbols during linking (porting to Plan9)

[Jens Staal]

Dear all,

I am currently trying to compile Bash on Plan9 (9front) using APExp (a
GNU/posix compatibility environment). I have all the bash object files
and libraries compiled and I only get one weird issue during linking:

chdir: BC: not defined
chdir: PC: not defined
chdir: UP: not defined

grepping the libraries shows that chdir is in libbuiltins.a
and that should correspond to builtins/cd.def

When I look in that file I do not see any references to BC, PC or UP and
I can not find anything obvious that would pull in those?

Any idea how to solve this?

Thanks!
