This isn't really a core Ruby question. This should be asked on
ruby-talk or (if there is one) the One Click Installer mailing list.
What is required to finally migrate Ruby builds on Windows to VC8?
A recompile of ANY library that an extension depends on, because of
rampant Microsoft incompatibilities. The problem is that any time you
have more than one application using more than one C run-time (e.g.,
MSVCRT.DLL and MSCRT80.DLL), you have different memory allocation
tables, different file handle tables, etc. Microsoft simply DOES NOT
CARE about this and won't provide any workarounds to make this clean
and easy.
It is not in the One-Click Installer's mandate to recompile OpenSSL
using VC8 instead of VC6. Or zlib. Or pdcurses. Or ...
VC8 is the best compiler available right now and the only choice for
64-bit Windows. Maybe we can talk to Intel about using the ICC if
they'll be compatible. But Microsoft never responded positively with
any way to work around this given that we don't control the library
chain end-to-end.
It's not a problem for most of Microsoft's customers like my
workplace, where we compile EVERYTHING we need from scratch (except,
of course, Windows) or can demand up-to-date libraries from our tool
vendors (or pay for them...). It is a problem for any open source
project, not just Ruby.

Yes, let's take this to Ruby-Talk so we can all participate. Most of the open source projects I deal with on Windows have gone to || stayed with MinGW/MSYS and its friends. Ruby seems to be the exception. I remember the past discussions and my own point of view was that it didn't really matter to me as long as the gems && other C/C++ libraries were available in binary form and in source form if their licenses required it. I don't *need* to build from source on Windows, although I wouldn't refuse the opportunity to do so.
I am in the process of phasing out Cygwin usage at my day job. I brought it in as a crutch and it has become a maintenance nightmare. The worst part of it is that it hoses up file and directory permissions at the NT level if you aren't careful (and I haven't been). :)
So while I know that VC8 is a "better" compiler than MinGW/MSYS, what other open source projects, if any, use VC8? How many others use VC6? What are the licensing gotchas on the Intel compiler? In general, are open source projects on Windows doomed to be second-class citizens? :(
