I presume that "Cygwin" folks would like to see this to be resolved by the
"linux kernel" folks ?

This is the (somewhat questionable) use of ipt_ECN.c and ipt_ecn.c in the
linux kernel. Windows filesystems are case insensitive, and see this as one
file.

Install and use Linux and be done with it.

I had not seen the ECN/ecn problem, but you will also be bitten by .S 
-> .s preprocessing. That's right about the point that I gave up, 
though on OS X I could have created a (case-sensitive) UFS filesystem 
rather than using a (case-insensitive) HFS one.

I maintain patches that allow building glibc on Cygwin and MacOSX.
The main patch deals with exactly this issue (S vs. s)
http://kegel.com/crosstool/crosstool-0.28-rc26/patches/glibc-2.3.2/glibc-2.3.2-cygwin.patch
I have to maintain it separately as the glibc maintainer dislikes the
idea of catering to Cygwin users (though maybe if I present it
as a MacOSX support patch he'd reconsider... naaah, probably not :-).

With the advent of linux-2.6, I also have a patch
to get kconfig to not use shared libraries (since I use kconfig
to help install the kernel headers, and shared libraries are tricky
to build on those two platforms).

It wouldn't be a big leap for me or someone else to also maintain
a patch to allow compiling the whole kernel on Cygwin or MacOSX.
If anyone puts it together, I'll carry it in crosstool.
