Sorry, but that's not the deal. Using my patches, you can install a
standard source tree, including gcc, gdb, binutils, [...], and last but
not least the winsup directory on, say, a Linux machine, and then build
a complete three stage canadian cross on *Linux*, which generates a
i686-pc-mingw32-x-arm-elf toolchain. You don't have to install the MinGW
libraries and header files somewhere on the Linux machine and tweak the
build process to find them. Everything comes out of the same source
tree. From my point of view this simplifies stuff, it doesn't make it
