12 Built in Scheme objects

Built in Scheme objects are mostly implemented in the C language portion of the source code, but many core operations are also reimplemented at the Scheme level. The overall definitions are in the C language file vicare.h (for the public API) the C language file internal.h (for the private API) and the definition of many values is duplicated in the Scheme language compiler ikarus.compiler.sls.
