LLNode Windows support

I thought I’d open this issue to discuss whether Windows support for LLNode is something anyone wants.

I’ve got and LLDB build up and running on Windows so I had a chance to try building LLNode on Windows. Running gyp_llnode worked fairly well.

The resulting Visual Studio project created by gyp required a little tweaking (mostly things I could google for). The main issue was that LLNode uses the getopt library which isn’t on Windows by default. Given that the getopt problem could probably be fixed running LLNode on Windows looks do-able but would need a bit of work and would probably break fairly quickly unless someone was using it regularly.

There’s two reasons why someone might want to do this:

• To debug issues with versions of Node running on Windows.
• To debug issues with core dumps generated on Linux. (LLDB is able to open Linux ELF cores even when it’s running on Mac or Windows.)

I’m not sure how important the first scenario is but the second one might be useful to developers with Windows machines who deploy to Linux. Of course you do have to get LLDB for Windows, probably by building it yourself, which isn’t hard but it is quite time consuming. (Developers with Mac’s who deploy to Linux are effectively already supported.)

Any thoughts? Does anyone else have a strong need for this? (I’m using a Mac so I’m neutral.)
