The package contains as well a collection of wrapper scripts and symlinks. Other java development tools from classpath are included in this package. The compiler can also generate class files. GCJ is a front end to the GCC compiler which can natively compile both Java(tm) source and bytecode files. This is a frontend to the GCC compiler to natively compile Java bytecode and source files. It passes the JCK (Java Compatibility Kit) and is compatible with Java 1.3, 1.4, 1.5, 1.6 and 1.7.
