[Chicken-hackers] pathname separator

[felix winkelmann]

Hi!

While testing a cross-built mingw32 chicken yesterday I came to the
conclusion that the whole "/" vs. "\" pathname directory separator stuff
is a total mess and just checked in a couple of changes that try to
clean that up. The slash ("/") is now used everywhereas separator char,
as the windows shell and mingw tools are quite happy without the backslash.
The pathname stuff in utils.scm now simply accepts both in most places.

I hope I haven't broken too much, please have a go at it, in particular
on native mingw and cygwin builds. Feedback would be very welcome.


cheers,
felix
