We use string comparisons internally to match file specifications in several places, but users can provide any legal combination of slash and backslash in specifying paths (dbpath, etc.). Moreover, Boost::filesystem v3's string() function prefers "native" path separator characters (so backslash on Windows).
We need to convert path characters to a common format (e.g. Unix-style "/") and use Boost::filesystem v3's generic_string() (or similar) so that string comparisons work as expected.

If you compare the file specifications in line 5 and 13 above, you can see the problem:
line 5 = /data/db/jstests_disk_repair/repairDir/backup_repairDatabase_0\jstests_disk_repair.ns
|
line 13 = /data/db/jstests_disk_repair\repairDir/backup_repairDatabase_0\jstests_disk_repair.ns
At the "pipe" character (|), the directory separators are not the same.
