I'm running into a similar issue to this trying to build with VS2015. I am seeing this error `unexpected ucrtbased.dll` appearing when my debug (MDd) build runs miniruby.exe
Where can I find the exact version of this dll required by this assembly language code?

----------------------------------------
When building debug build with MSVC (`-MDd` flag) then it will be linked to `ucrtbased.dll` where `_isatty` function obviously differs.

I've attached a patch which fixes this so that `__pioinfo` will be found for both debug and non-debug builds (x86 and x64)

Anyway I really really don't like this and I think Ruby should keep it's own fd <=> handle mapping and not use this hack, but for now this works until `_isatty` changes.
