Not least of it being that you shouldn't top post on mailing lists.

With recent autoconf, make sure you read the comments attached to that 
wiki article -- in particular the one about *not* configuring and 
building in the source directory.  If you have updated your MSYS make 
to version 3.81, it exposes a bug in autoconf, (which I know afflicts 
autoconf-2.61 through 2.63), and which makes it impossible to build 
using the above commands.

You should build in a separate directory, outside of the source 
hierarchy; that's actually good practice to adopt for *any* package, 
unless it absolutely does not support such a building method, (known 
as a VPATH build, and supported by any autoconfiscated package).

FTR, here's the sequence of commands I recommend, for building 
autoconf-2.63:--

  $ tar xzf autoconf-2.63.tar.gz
  $ mkdir -p build/autoconf-2.63
  $ cd build/autoconf-2.63
  $ ../../autoconf-2.63/configure --prefix=/mingw
  $ make
  $ make check
  $ make install

Do note that the `make check' step is optional; it confirms that the 
build has been completed successfully, but it  is rather slow -- it 
takes about 7 hours on my MSYS box.  If you don't care for the peace 
of mind it affords, you may omit it.

HTH,
Keith.
