You should not mount the whole Cygwin tree in textmode, it will always
give trouble when you expect it the least.  Just mount home dirs or
something as textmode, but even then refrain from it as much as possible.
There are tools out there to convert line endings, for instance d2u and
u2d.  I bet, if you count the cases where the conversion is necessary,
you will be surprised how _seldom_ it's necessary.
