Hello,

I noticed this issue while working on those directory-separator thing
for DOSish file-systems, and somehow this looks odd to me. For some
reason the filenames.h header assumes for cygwin DOSish file-system,
but in fact cygwin uses POSIXish file-system. I assume this definition
was caused by the times cygwin compiler had -mno-cygwin option, but
well I think we should correct this by following patch.
Dave, might it be that I am overlooking here something obvious, why
cygwin should assume DOSish filesystem?

Regards,
Kai
