[llvm-commits] CVS: llvm/lib/System/Win32/Path.inc

[Reid Spencer]

Changes in directory llvm/lib/System/Win32:

Path.inc updated: 1.60 -> 1.61
---
Log message:

Add a uniqueID field to the FileStatus structure for Paths. This will map
to the inode number on Unix and something far less unique on Windows. The
windows case needs to be improved.
