Fixes:
[cast] redundant cast
[rawtypes] found raw type
[serial] serializable class has no definition of serialVersionUID
Also suppress warning: auxiliary class TargetLanguageBase in ./inherit_target_language.java should not be accessed from outside its own source file
Adjust the floating point constants to be 1.125 and 2.25 (which
can be exactly represented in base-2 floating point) instead of
1.1 and 2.2 (which can't). This avoids problems on platforms where
floating point calculations suffer from excess precision, the most
commonly used of which is x86 when using 387 FP instructions.
