[Libjit] Compiler warning in jit_function_apply_vararg

[Eli Zaretskii]

Compiling jit-function.c produces the following warning:

     libtool: compile:  gcc -static-libgcc -DHAVE_CONFIG_H -I. -I.. 
-I../include -I../include -I. -I. -fno-gcse -g -O2 -Wall 
-fno-omit-frame-pointer -MT jit-function.lo -MD -MP -MF .deps/jit-function.Tpo 
-c jit-function.c  -DDLL_EXPORT -DPIC -o .libs/jit-function.o
     jit-function.c: In function 'jit_function_apply_vararg':
     jit-function.c:903:8: warning: variable 'entry' set but not used 
[-Wunused-but-set-variable]
       void *entry;
             ^~~~~

Looking at the code, I see that it computes 'entry', but then uses
func->entry_point:

        if(func->is_compiled)
        {
                entry = func->entry_point;
        }
        else
        {
                entry = (*func->context->on_demand_driver)(func);
        }
        [...]
        /* Apply the function.  If it returns, then there is no exception */
        jit_apply(signature, func->entry_point, args,
                          jit_type_num_params(func->signature), return_area);

Should the call to jit_apply use 'entry' instead?

Thanks.
