[Boost-users] [Regex] Why does this example code not compile?

Using g++ on a GNU Ubuntu Linux 7.04 machine, I am unable to compile the
boost example code (saved as test.cpp) at

http://www.boost.org/libs/regex/example/snippets/partial_regex_match.cpp

Although I can compile my own code which does not use boost, I get a lot of
garbled output from the example code...part of which is listed below.  Any
ideas on what is wrong and how to fix it?

Thanks.
