Hi,
 
I'm trying to build boost using MSVC compiler, and I want to change the default warning level from W3 to W4, but I don't konw how to pass this option to the command line.
 
For example, my build command is this:
"b2  --toolset=msvc-10.0 --buildtype=complete stage"
 
How could I pass the warning level to the compiler?
Thanks a lot for any help here.
 
 
 
Best regards,
