etags does not recognize function definition in C file |

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.
