Hallo, As I mentioned in a previous post I'm in the process of submitting patches for the official inclusion in Boost of the fixes contained in the custom 1.35 distribution that currently ships with CodeGear's C++ Builder 2009. However some of these fixes do not adhere to Boost standards and need some rework before they are accepted. This is a task for which I could do with some help! Specifically I'd be very grateful if someone could take the patch I posted here: http://svn.boost.org/trac/boost/ticket/2346 and modify it to comply with the requests placed by John Maddock in his comment. Thank you in advance! Cheers, Nicola -- Nicola.Musatti <at> gmail <dot> com Home: http://nicola.musatti.googlepages.com/home Blog: http://wthwdik.wordpress.com/
