RE: [boost] Re: time_duration test bug in Boost 1.30.0

The problem is in previous version of lexical_cast - new version works fine.
bug-fix release 1.30.1 should be OK.

PS The date-time example 'days alive' test is interesting, but a version which
tells one the number of 'days to still to live' would be much more interesting
;-)

| PS There are also lots of confusing warnings, most, if not all, of which I
| suspect could be casted away.
| It would be really nice to get a clear compile, preferably in strict mode,
| because this code is likely to be included by most user stuff, which will
| repeatedly produce a host of junk warnings.
|
| (And other MS specific unhelpful warnings which could be dealt with by
|
| #ifdef _MSC_VER  or BOOST_?
| #pragma warning (disable : 4800) // inefficient bool conversion?
| #endif
|
| As a general point, is there any reason why 'known to be unhelpful' warnings
| like this cannot be disabled in Boost code?
