librbcodec users must provide these two files when the library is built. rbcodecconfig.h provides configuration #defines and basic types, and will be included by public librbcodec headers, so it must not conflict with the user's code. rbcodecplatform.h provides various OS functions, and will only be included by source files and private headers. This system is intended to provide maximum flexibility for use on embedded systems, where no operating system headers are included. Unix systems can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with minimal changes.
