Please note that u-boot contains code that is supposed to run on the build
host (rather than on the target), so you also need a native cygwin compiler
which creates code for your x86-WinNT box. The "tools" directory above is
such a directory containg tools for the host.

On a regular Linux system, you usually call the make like this:

  make CROSS_COMPILE=powerpc-linux- all

The Makefiles then know where to use the "$(CROSS_COMPILE)gcc" and where to
use the regular host "gcc". Be sure not to mix that up.

In general, I see no reason why u-boot should not be compilable under
Cygwin. Getting there can well be a bit bumpy, though :-)

Marius
