Support for Windows cross-compilation from Linux (#295) 

Since `DirSep` matches the default separator of the target OS, it's
not suitable for performing path operations during compile-time on
the host OS.

The particular fix here solves the issue for cross-compiling a Windows
build from a Linux host, but Nim seems to need a more general solution
for detecting the host OS during compilation, so a host OS specific
separator can be used in paths derived from `currentSourcePath`.
