I'm using x86 Red Hat Linux 6.2.

Compile the appended java program (probably any program will do) like
this:

    gcj --main=x -g -o x x.java

Now debug it with the latest cvs trunk gdb:

    gdb -nw ./x

Now try to set a breakpoint like this:

    b 'x.main<TAB>

gdb just beeps at me.
So close the quotes and press enter:

    (gdb) b 'x.main'
    the class x does not have any method named main
    Hint: try 'x.main'<TAB> or 'x.main'<ESC-?>
    (Note leading single quote.)

Now try again:

    b 'x.main<TAB>

I get:

    (gdb) b 'x.main(java.lang.String[])' 

I think this must be a bug.  I expected:

* First, that TAB would work correctly the first time.

* Second, that b 'x.main' would work anyway, since it is unambiguous.
  (I only found the first bug because gdb has basically been forcing
  me to hit TAB all along...)
