I have uploaded the small logging object I proposed a few weeks ago
with some changes following Andrey remarks.

I think it's fixed now...

ADL does not work with old compilers (msvc-6.0)

Got to think about that.
It also compiles with bjam v2 now on a 1.34.0.
And it also compiles when added in multiple source files (hum).
Here it is: (http://minilien.com/?2oscdAofQK)
Just download it in boot_1_34_0 and unzip it.
Allow formatting per sink.
Allow max level definition per sink.
Allow severity/level definition.
