Actually, I lied. It turns out that it DOES matter. I need the source
location of the function header itself.  So:

1   void
2
3     foo(
4       int x
5
6   )
7
8  {
9     ...

I need '3' to be my base for all the relative offsets I get from the
profiler.  So, how do I find out the line number of the symbol 'foo'
itself?


Thanks.  Diego.
