+
Specifies the operating system for which the code is to be generated. The
compiler you used should be the compiler for that operating system. This option
causes B2 to use naming conventions suitable for that operating
system, and adjust build process accordingly. For example, with gcc, it
controls if import libraries are produced for shared libraries or not.
