[Mingw-users] how do I compile GCC?

[Jonathan W. <jo...@tp...>]

I have gcc-g++-3.3.1-20030804-1-src.tar.gz, 
gcc-core-3.3.1-20030804-1-src.tar.gz & 
binutils-2.14.90-20030807-1-src.tar.gz from the MingW download page.

What do I need and what do I do/run in order to get a working MingW GCC 
build going?

Also, how would I go about contributing changes to MingW binutils and MingW 
GCC? (I wanna add Thread Local Storage support)
