Web site suggestions

Greetings,

With regard to https://www-sop.inria.fr/mimosa/fp/Bigloo/manual.html

1.  The link to http://www-sop.inria.fr/indes/fp/Bigloo)%20/doc/r5rs.html
appears bad.

2.  Section 6 refers to fair threads but doesn't mention native threads.
Given how important threads are these days, some people (me) might see that
and incorrectly lose interest in Bigloo.  I would suggest adding at least
one sentence that says that Bigloo also supports native threads.

Thanks!

Blake
