How is this collision? Not too familiar with msvc dll export libs.

If I understand correctly the lib you need to link to use "hello.dll" is
called "hello.lib". The dll libs aren't put in the same directory so is
that really an issue?

g++ (GCC) 3.4.5 (mingw-vista special r3)
ln (GNU coreutils) 5.97

Even if MinGW at some point looked for "libhello.lib" you'd still have
the issue of MSVC not finding "hello.lib". Surely must be a way to make
them both happy so you don't have to rename libs every time you build or
keep compiler specific settings for all static libs in the Jamfile?
