Crash in java_lang_Double.c with kissme

[John Leuner]

The code in java_lang_Double.c was crashing with my JVM (kissme) because it was 
failing to recognise the infinity values.

The following patch fixes the crash, but there are still many mauve failures 
(which might be causes by kissme or classpath)

The comparison was failing even though the two values have the same binary 
value (when printed out in gdb).
