Hi,

It it okay to merge the mpl part of this change to release?

http://svn.boost.org/trac/boost/changeset/48960/

It fixes a preprocessor error in gcc 4.4 which stops a lot of
libraries from working with that compiler. The python part of the
patch isn't required, the error is due to mpl's preprocessed headers
not including the boost preprocessor headers and doesn't occur in
other libraries that use iteration, as they always include the
headers. I've had a look through the test results and everything seems
to be working.
