Don't much like these, I must say. Can't we just wrap the variable name in
a function-style macro as follows:
  gcc ... '-D_U_(var)='
then have function arglists such as
  int aFunc(XtPointer _U_(unused1), UserArg _U_(unused2));
and for compilers that don't like unnnamed args, use '-D_U_(var)=var'
instead?
