There are problems with the large, interesting abc package.
Some have already been identified (i.e. the getwd() business),
although the suggested patch as posted does not seem to clear
them up yet - a minor point, though.
Another one is the way program brand, inside Setup, goes about
identifying the kind of Unix one has.  It FIRST sees if SIGCHLD
is #defined, and if so, it EXCLUDES that one may have an AT&T
System-V variant.  But I have tried it on both Interactive
System V/386 3.2 version 2.2, and HP/UX 7.0, two Sys/V flavors,
and BOTH *do* define SIGCHLD *as well as* SIGCLD; so it seems
Setup has it upside-down.  I have changed it to FIRST test for
SIGCLD (as identification of Sys/III or Sys/V), and only if that
is not set if SIGCHLD then tested.  This way, both of my systems
are correctly identified as S/V.
With this change, all the compilations in the make go flawlessly.
Unfortunately, there seems to be LOTS of pieces missing; the
linking step collapses in flames.
Here are the unsolved references, from ld error message reformatted
to save several lines:
_main _ptnsyze _setintrhandler _resetintrhandler _help _slowterminal
_hushbaby _int_mod _int_ldiv _int_quot _nodetype _node5 _node2 _node3
_node1 _node4 _node6 _node8 _node9 _mk_ref _wsp_arg _is_gr_reccall
_bws_arg _stripped _split _upper _lower _choice _mk_fun _mk_prd _initsig
_use_bed _ins_range _mk_rbounds _mk_trimloc _mk_tbseloc _mk_simploc
_mk_how _mk_indirect _ask_for _mkchar _getwd

I have the same, identical set of unsolved externals, both on
HP/UX and on Interactive 2.2.  Some appear to be minor problems
related to above-mentioned glitches, e.g. getwd; others look a mite
more FUNDAMENTAL - eg. main!; but there are just SO many of them,
that I can't think of any simple explanation for them all, unless
it be a missing piece!  What gives?  Awaiting with interest... this
one seemed like a nice Christmas gift to start teaching programming
to my son - pity!
