MSVC *is* continuously checked; see
http://google1.osuosl.org:8011/builders/clang-i686-xp-msvc9.  Anyone
who breaks the MSVC build will get a nastygram from buildbot.

Please note that the MSVC buildbot only builds the X86 target at the moment.
I don't know why though.

This is new news for me.

If the developer who broke the msvc build receives a nastygram, would he
urged to fix it when he has no msvc compiler and probably no Windows
machine either? The "don't break the build" mantra applies to *nix
only. No LLVM developer will be bashed for breaking the msvc build.
Which is understandable: the pain of multiple compiler C++ support is
too much for mere mortals.

Anyways, that buildbot only checks one msvc compiler (right?). It is not
infrequent a broken build on some compiler version for a long time.

Technically it doesn't send nastygrams either, all though so far we've
done a good job of noticing when it breaks.

Because my Win32 box is super slow. :)

It made more sense when I was ironing out kinks, now that it works its
probably worth switching it back.

The big problem with the windows builder is that it doesn't run any
tests, so while it makes sure things build, it doesn't make sure they
work (as well as they do).

It is frequently possible to unbreak the build just from reading the
log. In practice this isn't that different from Darwin vs Linux,
except that MSVC likes to break more often. :)

Right. If we get developers who care about MSVC (and want to do
something about it) they are welcome to fix this.
