Re: [boost] [lexical_cast] performace patch

It would be nice at the same time if you could ensure that lexical_cast doesn't produce a blizzard of warnings if compiled in "strict" mode (MS level 4). OK, I'll check it.

I also note that the expression for calculating the precision is STILL wrong and will fail loopback tests, and especially annoying to serious with serialisation. I thought this had been corrected at 1.34. I remember this problem. It is next in my list of lexical_cast improvements. Not sure that loopback test is solvable, though. Thanks for the links, they will help to refresh my memory.
