[boost] [1.34.0] failed to build on cygwin

13 May 2007

      I run "bjam install --toolset=gcc-3.4", and this is the output:

Building Boost.Regex with the optional Unicode/ICU support disabled.
Please refer to the Boost.Regex documentation for more information
(don't panic: this is a strictly optional feature).
