I think you are not looking for -mrtd but for versioned symbols.

-mrtd does:
"Use a different function-calling convention, in which functions that take a
fixed number of arguments return with the "ret" num instruction, which pops
their arguments while returning."

According to the assembler that seems to work. I have frankly no idea how to do
symbol versioning and I have to admit I failed to find any usable information
on  the net, the closed comes the glibc implementation notes at:
http://people.redhat.com/drepper/symbol-versioning

By far not sure whether the following works, but it produces the right symbol:

asm(".symver simple_sub, simple_sub@N42");
void simple_sub(int *a,int *b)
{
  *a = *b;
}

$nm foo.o
0000000000000000 T simple_sub
0000000000000000 T simple_sub@N42

I have no idea how to do it properly and I don't know how to do it in Fortran.
You are probably better off in asking this question in a mailing list.
