This is a good question. As always I recommend that you add yourself to
the MS4W ticket for this issue
(http://bugzilla.maptools.org/show_bug.cgi?id=2037) and add to the
discussion, thank you.
I was having problems compiling the ECW support with their old SDK,
however there is a new SDK released Oct 2009 that compiles on my
platform. *But*, there is a license change for the ECW SDK. For an
excellent detailed discussion on this change please see a recent
GeoServer email thread on this
Paul Ramsey (from OpenGeo/PostGIS) summarized the license change to me
as "you can use the ECW library if your software *and* the things you
use that software *for* are entirely 'noncommercial'".
I don't feel that ECW can be supported by MS4W due to this new
restriction (MS4W users have no way to know about this license).
