I believe this is a known problem: there is a fix in the works but you may 
have to wait a while: the problem occurs if you include the platforms native 
<regex.h> before including <boost/regex.hpp>, I believe in some modes IBM's 
compiler includes <regex.h> if you include nearly any platform header.  You 
could try moving <boost/regex.hpp> to be the first include, if that doesn't 
fix it, it gets harder, because the "correct" fix is a complete 
restructuring of the Boost.Regex header structure.  I believe that our AIX 
regression tests were passing for Boost.Regex so there is a set of compiler 
options that will also remove the problem, our regression tests are using 
something like:

    xlC  -c -DNDEBUG -O3 -qstrict -qinline  -qnotempinc -qfuncsect -qeh -qrtti 
source-file.cpp

but I don't know which of those is important,
