Getting started on testing and reading documents

[Archimedes Submerged]

I have a few questions.

1.  How to build and read the svn version of concept guide?  Is the copy on
the web the same?
2.  (gnucash:16742): GLib-GObject-WARNING **: invalid cast from
`GncEmbeddedWindow' to `GncMainWindow'
I want to debug the above message.  What does the 16742 mean?
3.  When I choose "since last run" under actions/scheduled transactions, I
get many transactions listed in "auto created transaction list".  Maybe this
is because the last thing I did last summer was import lots of stuff from
QIF files I made from the PDF files Citibank provides for years back
statements.  I wanted to look in the documentation to see under what
circumstances transactions get created and why am I hearing about them now?
google for "site:cvs.gnucash.org auto-created" did not find anything in the
concept guide but it did lead to code related to the subject.
4.  Anyone know what this gdb warning means:
(gdb) attach 29355
Attaching to process 29355
warning: The current VSYSCALL page code requires an existing execuitable.
Use "add-symbol-file-from-memory" to load the VSYSCALL page by hand

In more detail:

I've started working on my gnucash files, untouched since last August.  I've
got svn revision 14341 built with enable-debug and with no -O2 so gdb
doesn't get confused.

$ PATH=/opt/gnucash/bin:$PATH PKG_CONFIG_PATH=/opt/gnucash/lib/pkgconfig
make distclean
$ svn update
$ CFLAGS=-g PATH=/opt/gnucash/bin:$PATH
PKG_CONFIG_PATH=/opt/gnucash/lib/pkgconfig ./configure
--enable-compile-warnings --prefix /opt/gnucash --enable-debug
$ PATH=/opt/gnucash/bin:$PATH PKG_CONFIG_PATH=/opt/gnucash/lib/pkgconfig
make
# make install

I want to know how to build the latest documentation.  I'm looking at
http://wiki.gnucash.org/wiki/Concept_Guide

I ran
$ svn checkout http://svn.gnucash.org/repo/gnucash-docs/trunk gnucash-docs

and reran the build, but it didn't seem to do anything with the document
files.

Is http://cvs.gnucash.org/docs/guide/ the latest version?
