Get undefined reference to `sh_xfree' In function `write_helpfiles'.
Anyone run into this... was it a mistake to try for separate help
files?
Thanks for the report. It's a simple patch, so I've attached it.
----
FWIW -- my workaround was to remove the "--with-separate-helpfiles" option.
As it seemed to be called in something to do with the helpfiles.
Also of note, a parallel make often fails ...
Should I assume that the bash-make isn't multi-process safe? Or
is that unintentional?
It's just a missing dependency. I wonder why I haven't run into this
before; I run `gmake -j 4' to build bash on every system I use.

I often will use "make -j" for most things....
A limit sometimes will improve efficiency on large builds (ex. kernel),
but difference is negligible w/many builds.
Also, haven't begin to look at "why", but something is alot slower
in bash-43...
Noticed it during login.
Added a -x at beginning of profile.sh with a function
to print "SECONDS+a millisecond counter".
To get to beginning of calling my first "personal file"
(~/.bashrc): bash43 shows:
[ 108.973]/etc/profile#356> test -r /home/law/.bashrc
[ 109.999]/etc/profile#356> . /home/law/.bashrc
-------------
bash42 shows:
[ 24.084]/etc/profile#357> test -r /home/law/.bashrc
[ 24.090]/etc/profile#357> . /home/law/.bashrc
....finishes in a bit over 31 seconds...
----
Note--- real login time <1 second max in 4.2 -- including
my personal scripts, the 24 & 31 are w/the tracing overhead, so
divide by ~20 -- bash43 seemed like several seconds -- most of which
was in the suse setup. but haven't narrowed it down anymore
than coming up with the raw data...which I could dump on you
if you wanted it -- up to the point where it starts to call
my .bashrc -- i.e. before that would be all suse's intro scripts.
I've no idea why there is such a large discrepancy at this point.

When I noticed the time problem, I made sure bash was
stripped (strip /bin/bash) & made sure it was "prelinked"
