The instructions have not changed, since the basic framework is exactly
the same. What problems are you having??

Here's my quick 1st cut:

1. Pick a prefix, say /usr/local/cross-tools (I'll call this $prefix
   from now on).
2. Populate $prefix/i386-mingw32/{lib,include} with mingw + windows32api
   headers and import libraries.
3. Get and install binutils. If you don't have access to Cygwin b20.1
   sources (binutils 2.9.4), use the standard binutils-2.9.1, which mostly
   works. It is missing a few pieces however, such as enhancements to
   dlltool, dllwrap, etc.

   $ cd binutils && mkdir obj && cd obj
   $ ../configure --target=i386-mingw32 --prefix=/usr/local/cross-tools
   $ make 
   $ make install

4. Get egcs-1.1.1, patch it with my changes from
   ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/egcs-1.1.1/patches/
   and build/install:
  
  $ cd egcs-1.1.1 && mkdir obj && cd obj
  $ ../configure --target=i386-mingw32 --prefix=/usr/local/cross-tools
  $ (cd gcc;  make installdirs)
  [ the above step is needed due to relative path lookup for includes/libs ]
  $ make 
  $ make install

Done.

If you already have Cygwin b20.1 sources, and can live with egcs-1.1,
you're all set:
  
  $ cd cygwin-b20.1 && mkdir obj && cd obj
  $ ../configure --prefix=/usr/local/cross-tools --target=i386-mingw32
  $ make 
  $ make install
