We will see. While some basic libraries are multi-compiler packaged like
strigi and win32libs, other package does not have such support. Recent
Qt release for mingw and msvc are using the same dll prefixes/suffixes.
I had submitted a relating patch to trolltech (mingw should have lib
prefix) but it will need some time to be in the main stream. May be we
have to fix more libraries.
Currently I'm using a separate installation root for mingw and msvc to
avoid interferences caused by loading wrong dll's. When the kde
packaging once is stabilized, we can design how to have common runtime
binaries. The most important thing today is to have a stable source base
to be able to build packages with a livetime at least more then a few
day :-)

A note about size of runtime binaries in the currently packaging mode.
kde support binary runtime (without kdelibs) needs about 30 MB
(win32libs,kdesupport,qt) and kdelibs binary runtime need about
additional 30 MB so that we have a sum of 60 MB for each supported
compiler. It may be that several dll's could be skipped in case of
single application packages, but we will see.
