Hi,

well, if you do want to compile everything from scratch, you will first 
need to update MSYS bash and coreutils. You may also need MSYS DTK to 
provide a perl parser (is that what you call it?).

Next, you can build the latest binutils from cvs checkout, or grab the 
pre-compiled binutils binaries from the MinGW site.

Then you will need and updated GMP and MPFR. They may be configured and 
installed with simply "./configure --prefix=/mingw --enable-static 
--enable-shared". They are needed for gfortran.

Next should be gcc itself, I do suggest taking a look at the 
gcc-4.2.1-build-dw2-2.sh shell script provided at MinGW sorceforge. It 
will provide clues to how gcc 4 should be configured and build.

Do not forget to read up the gcc install guide at 
"http://gcc.gnu.org/install/", it will save you a couple of hours of 
hard work due to mistakes.

Iirc, that should be all. Sorry if I forget anything, I need to sleep.
