[DynareDev] Boost libraries

Hi all,

Concerning the Boost libraries that are now needed to recompile the preprocessor:

- the 1.33 version distributed with Cygwin is too old: it doesn't contain the boost/graph/max_cardinality_matching.hpp header which is needed for model normalization. Stéphane: could you tell me which version of Boost is present in Ubuntu Intrepid (in Debian we have several possible choices: 1.34, 1.37 and 1.38). Maybe the version in Ubuntu Intrepid contains that header, in which case it should be fine

- installing the boost library normally consists of simply unpacking the archive. Since Boost is mainly made of C++ headers, there is normally no need to recompile anything

Best,
