> The JDK changes where needed to add a path to the libjvm.so library 
> when linking test executables.
> These changes where provide by Erik Joelsson.
>
> The Hotspot changes addressed the following issues:
>
> The StackGuardPages test directory needed to be added to the list of 
> native executable tests.
>
> The libjvm.so and libpthread.so libraries needed to be added to the 
> LDFLAGS definition for the
> "invoke" test executable.
>
> The StackGuardPages/testme.sh script needed to specify that 
> DoOverflow.java must be complied,
> specify the new location of the "invoke" test executable and remove 
> all portions of the script that
> compiled and linked DoOverflow.java and invoke.c.
>
> The native test source file "invoke.c" needed to be renamed 
> "exeinvoke.c" so the build system will
> automatically build it.
>
> The native test source file exeinvoke.c needed to be changed to 
> compile without warnings, pass the
> path of the DoOverflow.class file to the function which starts the JVM 
> and keep the linux gcc compiler
> optimizer from in-lining the do_overflow() function which caused it 
> not to get called.
