That's potentially a lot of work. I started looking at it and it would
involve hiding the OpenBSD library under some other lib/System facade.
Designing that facade takes time and we probably won't get it right
the first or second time.
Another option is to just provide the OpenBSD regex code as an optional
library that gets compiled and linked for MSVC systems. I'm not at all
familiar with MSVC build procedures so I don't know how involved that is.
The advantage to the second approach is that we keep the POSIX interfaces
in the rest of the LLVM code, we don't have to design another set of
interfaces and we just use the OpenBSD library when we have to.
