Re: [microblaze-uclinux] Doing an out-of-tree application and compiling under Windows

[John Prestwich <johnprestwich@xxxxxxxxx>]

So since I have not heard from anyone on this I assume
that either I sent my inquiry to the wrong place, or
it is a really stupid question and I should
intuitively know the answer, or the answer is that it
can't be done.  My question is which one is it.
