File globbing on windows

On Windows, when I try to use file globs, they don't work. FWIW, file globs work on linux.

Example

```
dir *.cpp
C:\Users\Belli\Documents\Code\emscripten\em++ *.cpp
```

yields

```
Volume in drive C is Windows7_OS
Volume Serial Number is 8E2A-26D8

```

so it is clearly not handling the glob properly.
