Why would you do that? There are pre-built MinGW binaries available on
sourceforge (octev.sf.net), including an enormous amount of pre-built add-on
packages as well.

Pre-built dependencies and other valuable stuff is here:
http://www.tatsuromatsuoka.com/octave/Eng/Win/

Anyway what gcc version do you use? Have you documented your steps? We would
be grateful if you did and could share with us how you did it.

I cannot add attachments from Nabble, so I'll add a few instructions below.
These were posted almost verbatim IIRC about a year ago in the
octave-maintainers list by me.

They were valid for Octave 3.5.0+ but I used them for building 3.6.2 and now
even 3.7.0+ as well (but for the current dev sources many other fixes are
needed, not yet documented).

Good luck,

Philip

#  The above modification required for liboctave/oct-env.cc and
src/oct-hist.cc.
#  Possibly this has already been done in liboctave/oct-env.cc

#==========Fixed==========================================================
# src/sys-dep.cc: error: 'TH32CS_SNAPMODULE32' was not declared in this
scope'
#See:
#http://hg.savannah.gnu.org/hgweb/octave/rev/2f42a7b0cf94

#==========Fixed==========================================================
# src/file-io.cc:129:7: error: 'unlink' is not a member of 'gnulib' 
#I faced the same problem.
#
#But I replaced gnulib::unlink with unlink.
#You need to do this two places.
#
#Then you'll get error-message that isatty is not a part of gnulib, or
something like this.
#Workaround: add include <io.h>. 
#
#Also in lex.cc: include <io.h>
#=========================================================================


#Other tools required for develpment source.
#  If you want build developmet source, the below tools are reuired.
#    * git  (PRN) download msysgit, make (using autoinstaller), copy all
newly created
#            files (7 files IIRC) into msys/bin
#    * (PRN) gnulib. download a snapshot from , untar/unzip
#    * Mercurial  (PRN) download tortoisehg
#
#  I am using the Cygwin to use those tools.


##<PRN>
## Set up mingw, msys, GNUwin32, OctaveLibs, gplibs directories somewhere.
## Add all ./bin directories (mingw/bin, msys/bin, ...) to the Windows PATH

## If you have ghostscript installed, be sure to add \full\path\to\gs\bin in
your Windows PATH,
## and -just to be sure- make a copy of the command line version
(gswin32c.exe) as gs.exe

## Adapt path settings in ..../gplibs/lib/pkgconfig/*.* 
.../OctaveLibs/lib/pkgconfig/*.*
## .../OctaveLibs/lib/*.la ..../gplibs/lib/*.la  
.../OctaveLibs/bin/fltk-config 
## .../OctaveLibs/lib/libhdf5.settings

## Download octave development sources. I use TortoisHG for that.

##</PRN>

# ==========================GNULIB===========================
## Get gnulib snapshot (easiest): browse to
http://git.savannah.gnu.org/gitweb/?p=gnulib.git
## right-click one of the "snapshot" words in the shortlog, and download the
.tgz snapshot.
## Next, in MSYS, do 

tar xvzf gnulib-<version>.tgz

## Then, aftger downloading Octave, in the Octave src dir do

./autogen.sh --force --gnulib-srcdir=/dir/where/you/untarred/gnulib-tgz-file

# ===== Cut and paste below into MSYS command terminal. Adapt paths where
needed ===========

make -i # make fails TeX error(?) so that reexecute make ignoring errors.

make check -i
make install-strip -i

Add in .octaverc:
setenv ("MAGICK_CONFIGURE_PATH", "/full/path/where/magic.mgk/lives")
(C:\Programs\Octave\3.4.2\share\GraphicsMagick-1.3.7\config, much like in
Benjamin's 3.2.4)

Good luck
