Just tried some tests out on the WinXP command prompt. This is really a bug
in the Windows command prompt. If you try this in a regular command
window...

echo "test"[space]>test
set A="test"[space]
echo "%A%">>test

...replacing [space] for a real space ;-) You get those spaces in the file.
It just so happens that the action is getting split and passed into the
command execution with the extra space :-(

My question is.. How does Comeau choke on it? That is; is it the "--"[space]
that's causing problems? Or is it the ""--"[space]" that barfs? And where in
Boost.Build is it doing that (link, cc, c++, archive, etc.)?

And more importantly.. what is it supposed to be feeding to Comeau? (can't
fix it if I don't know what it wants)
