It does not currently.  The pc.objcaseinsensitive flag is set if the OS is
case insensitive or the filesystem is case insensitive.  I was preparing a
patch to take the same case sensitive flag as lsattr uses for "C" into
account for pathconf, but I am unsure now how the case-sensitive directory
situation actually works out.  It seems like Cygwin would still pass the
OBJ_CASE_INSENSITIVE flag to the OS, I guess it doesn't respect that in a
case-sensitive directory?  Should pathconv check the directory case
insensitive flag when initializing caseinsensitive for the
objcaseinsensitive accessor?
