this patch updates coLinux build system for using gcc 4.1.2:
* Upgrade to gcc 4.1.2, binutils 2.16.91, mingw 3.11, w32api 3.8
An imported change is, that the gcc is unchanged (has no mingw patch)
and downloaded directly from http://www.gnu.org. The compiler shows many
harmless warnings about 'signedness'.
Have short tested. Colinux was running with initrd and debian rootfs image.
It's based on article and webside from mingw users list, thanks they :-)
