This seems like Boost.Build glitch. Does anybody know if that option
is can be safely dropped?

This appears to be a problem with Boost.Regex and is better reported
to Boost issue tracker at svn.boost.org. Be sure to try with 1.40
release and with SVN HEAD -- it might be already fixed. And also
include a minimal program that reproduces this issue.
