<body class='hmmessage'>ps: speaking of pre-reqs..m3-win/import-libs/m3makefile has a special hack to find my Visual C++ 2.0 toolset.<BR>
In this way the distribution can support any Visual C++ toolset, probably.<BR>
However this is not right in terms of letting anyone build a distribution.<BR><BR>
There remains an open question as to which toolsets to support, er, which Microsoft ones to support.<BR>
I built this with 8.0.<BR>
9.0 has been released now.<BR>
