Yes, that's what I was going to add.  This is how I normally work.
We build toolchains using a GNU/Linux host, including libraries.  When
our customers run the IDE on Windows, they get mixed debug
information; some has Windows paths, some has POSIX paths.  I think
that a best-effort approach to work with both is more valuable than
handling the few corner cases where that breaks down (e.g. paths
containing a '\' or ':' on a POSIX system).
