Comment (by lukester_null@…):

 Actually looking at it again, looks like it would throw up some warnings
 with VC++ and it does indeed:

 {{{
 basic_iarchive.cpp
 ..\..\..\libs\serialization\src\basic_iarchive.cpp(345) : warning C4267:
 'argument' : conversion from 'size_t' to 'const unsigned int', possible
 loss of data

 }}}
 ... and so on.

 It also throws up a bench of warnings about unsafe functions. I normally
 don't see those as _SCL_SECURE_NO_WARNINGS and _CRT_SECURE_NO_DEPRECATE
 get set in my build environment (not via bjam).

 So sorry about the confusion there. This was a patch I've been applying
 against boost for some time and I thought it was about time I mentioned it
 - but sadly forgot where it was generating the warnings in the first
 place!

 If I get some time I'll have a look with SunStudio but hopefully the VC++
 warnings can be removed in the meantime?

 Best regards

 Luke Elliott.
