We haven't tested Igloo with the VC++ 6 compiler. If it doesn't work I
don't think we will attempt to fix that (unless it is a simple fix).
If you haven't tried yet, there is a suit of tests that comes with
Igloo (under the tests directory). If you can compile and run those
tests, everything should work.
Good idea about the making compatible compiler versions visible on the
page. Our testing strategy for different environments would need a bit
more structuring as well.
