c++ symbol name

[Martin Stecklum <martini_stecklum at gmx dot net>]

Hello,
I need to define a specific symbol name for a function in the resulting 
object file. example:

test.cpp:

int test();

int test()
{
	//do something
	return 0;
}

I compiled the file using:
gcc -c -fno-rtti -fno-builtin -fno-exceptions -nostdinc++ test.cpp -o test.o

(Yes, I want to create a freestanding application!)

The symbol name for the test() function in the resulting test.o file is 
"_Z4testv":
readelf -s test.o

Symbol table '.symtab' contains 8 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name
     0: 00000000     0 NOTYPE  LOCAL  DEFAULT  UND
     1: 00000000     0 FILE    LOCAL  DEFAULT  ABS test.cpp
     2: 00000000     0 SECTION LOCAL  DEFAULT    1
     3: 00000000     0 SECTION LOCAL  DEFAULT    2
     4: 00000000     0 SECTION LOCAL  DEFAULT    3
     5: 00000000     0 SECTION LOCAL  DEFAULT    4
     6: 00000000     0 SECTION LOCAL  DEFAULT    5
     7: 00000000    10 FUNC    GLOBAL DEFAULT    1 _Z4testv

So here comes my question. How can I define the symbol name for the 
test() function for example to _test?

Bye
