Is there something that can be configured to change how gcc reports its search
path? I've used different builds of MinGW-W64 and some end up with at least
one standard header path that is completely forward slashes and some end up
with only paths that have at least one backslash. Usually, for the paths that
have a backslash, gcc reports a fully forward slash path as a duplicate and
ignores it.
Another tool that I use, gccxml, cannot interpret paths with backslashes.
Obviously, that's not a MinGW-W64 problem, but I thought maybe I could
workaround it since I've noticed different behavior with various MinGW-W64
builds.
