etags does not recognize function definition in C file

[Alexandru Harsanyi]

This is actually a bug in the etags program not emacs.  For the  
following C
file:

-----
#include <stdio.h>

int flag = 1;

void foo()
{
    if (flag)
    {
//        bar();
    }
}

void bar()
{
    printf("bar\n");
}

void baz()
{
    printf("baz\n");
}
-----

If I generate a TAGS file using the command:

  etags tags_bug.c

the resulting TAGS file will not contain an entry for the 'bar'  
function.  I
believe this is caused by the empty if block in the 'foo' function.   
If I
uncomment that line, the TAGS file will contain an entry for 'bar'.

Best Regards,
Alex.
