-  Title:       WINDOWS DEPENDENCY GENERATION
-  Description: Dependency generation is currently disabled when a Windows native
-               toolchain is used in a POSIX-like environment (like Cygwin).  The
-               issue is that the Windows tool generates dependencies use Windows
-               path formatting and this fails with the dependency file (Make.dep)
-               is include).  Perhaps the only issue is that all of the Windows
-               dependencies needed to be quoted in the Make.dep files.
-  Status:      Open
-  Priority:    Low -- unless some dependency-related build issues is discovered.
