Well, strictly speaking yes, but in practice you can often get away
with just using forward slashes. For example, cygwin does enough for
xsltproc to work with windows paths (back slashes and all) until you
use a relative path like "../lookup.xsl". When resolving this it seems
to assume that the separators in the base path are forward slashes, so
it messes up the path. You can get away with a 'c:/xxx/yyy/zzz'
because for the most part it just treats the paths as text, and cygwin
handles the rest.

So the logic would have to be in individual toolsets rather than
generic? That's a pity.

Can the cygwin bjam successfully call non-cygwin programs (such as
Visual C++ and quickbook built using Visual C++)? I'm asking about
this because it'd make building the documentation much easier if boost
build could use both cygwin and non-cygwin programs. If this requires
some extra configuration in user-config.jam that's fine - the
difficulty saved would more than make up for it.
