[9] Fix for JDK-8074824: Resolve disabled warnings for libawt_xawt

[Phil Race]

It is not always clear to me what warning is being suppressed and why you have
chosen a particular solution/action


this next one looks like it might introduce an unused variable warning.
What was it solving ? That the code was not checking a return value ?

size_t bytesWritten = write ( AWT_WRITEPIPE, &wakeUp_char, 1 ); //bytesWritten is unused


Isn't the compiler's point here that you *should* be doing something with the result?
Not just ignoring it differently ...

and this one ? I want Semyon to comment on what this code is trying to do
in its original form since it was added for GTK3.
