No doubt -- you don't use any "toolset-specific requirements" or how they
are exactly named, "conditional" requirements. You just add unconditional
requirements <cflags>-wd4996 and <cflags>-Wno-non-virtual-dtor

Did you read:
http://boost.org/boost-build2/doc/html/bbv2/tutorial/conditions.html

which gives the exact syntax? 

For msvc, you'd use: <toolset>msvc-8.0:<cflags>-wd4996
