Hi Volodya,

<dependency>svnrev.h fixed my problem, thanks !
But i tried to include svnrev.h in main.cpp but i didn't succeed 
(svnrev.h not found) even if i applied your given patch.. but i have 
an old boost-build... I tried to download the newest version from
cvs but my bjam.exe is too old. I will check with the new one if it 
is ok.

Thanks

Renaud
