Kenji,

Let me make sure I understand what you're trying to do:
You're trying to translate a *Windows* path to a Windows path using
cygpath?

The '-p' flag tells cygpath that the path it's translating is in the form
of Unix $PATH (i.e., directories/files separated by *colons*).  Thus, it's
trying to translate the 2 component Unix path, 'c' followed by '\', into a
Windows %PATH%-style list (directories/files separated by semicolons).
This is correct behavior, and exactly what you're seeing in 1.3.15.  Any
other output is erroneous, and should be treated as such.  1.3.14 cygpath
apparently had a bug.  It's quite possible that the change you mentioned
had the additional benefit of fixing this bug.
	Igor
