I'll post some results for completeness, even though it's years later. The 
one pathname problem I've had has been that (directory (make-pathname :type 
:wild :name :wild)) produces an error or (if built with -DNO_SMALL_SSTRING) 
a NIL. If that's the same problem as what you referred to then:

I have observed the problem on:
a) Windows XP 32-bit, Cygwin 32-bit, targetting Mingw 32-bit, and
b) Windows 10 64-bit, Cygwin 32-bit, targetting Mingw 32-bit, and
c) Windows 10 64-bit, Cygwin 64-bit, targetting Mingw 32-bit

I have observed the problem's absence on:
d) Windows 10 64-bit, Cygwin 64-bit, targetting Cygwin 64-bit, and
e) Windows 10 64-bit, Cygwin 64-bit, targetting Cygwin 32-bit
