To be honest I am not qualified to give an answer since I can only test
on gnu-linux based machines.

But if you only need an extra underscore to make this work on your
platform then what you can do is add a new boolean system property
"gnu.gcj.runtime.NameFinder.demangle_extra_underscore" or something
similar that tells NameFinder whether to add an extra underscore to the
mangled function name before demangeling it (use it in
NameFinder.demangleName(String)).
Then you can add some logic in java/lang/natRuntime.java
java::lang::Runtime::insertSystemProperties() to set this property to
true for the appropriate platforms.

See the GCJ manual for the other system properties used by NameFinder:
