	Even though the "kernel" (cygwin 1.5) doesn't support unicode
shouldn't it be possible -- and desirable for gcc to support the
'wstring' datatype?

	It does seem 'wstring' is supported on standard linux,
but internally, the kernel doesn't support double-wide
characters anymore than cygwin.  So maybe the problem is
not that cygwin doesn't support unicode, but that the gcc
libs & compile utils don't support the standard linux
equivalents?

	Whether or not cygwin (or the linux kernel) supports
"wchar" is not entirely relevant to what the application libraries
on top of the kernel support -- at least going by the example
on an x86_64 linux.  It's still the case that the 64-bit
linux kernel doesn't support wchars any more than cygwin, yet
the compiler suite does.
