Hi. I have some small problems with 0.4.

I'm running Mandrake 8.0, Ruby 1.6.4 (and 1.6.5), gcc 2.96

<SNIP>
g++ -fPIC -O3  -pipe -mcpu=pentiumpro -march=i586 -ffast-math
-fno-strength-reduce  -I/usr/lib/ruby/1.6/i586-linux-gnu -I/usr/include

-I/usr/X11R6/include -c -o flmenu.o flmenu.cc
flmenu.cc:145:20: warning: extra tokens at end of #undef directive

</SNIP>

This all compiles, but those warnings look scary. Is this something I
should worry about?

But I also got the ol' rb_gc_mark problem.

<SNIP>
flwidget.cc: In function `void rb_fl_mark (Fl_Widget *)':
/usr/local/lib/ruby/1.6/i686-linux/intern.h:189: too many arguments to
function `void rb_gc_mark ()'
flwidget.cc:34: at this point in file
</SNIP>

But this seemed to be the GCC 2.96 fault.
I changed the intern.h of Ruby to read
	void rb_gc_mark(VALUE);
and the flwidget.cc in ruby-fltk to read
	rb_gc_mark( (long unsigned int)(userdata));

I know, I should update :-)

Now, as for something _functional_ I'm missing. FL_SYMBOL_LABEL.

I was hoping for find SYMBOL_LABEL constant in Fltk, as I want my
buttons to show those nice arrow pictures. When I didn't find, it I
tried this:

	10.times{|i|
	  upbutton = 
	    Fltk::Button.new( x, y ,butw, h/(4*3), '@#2<-' ).
	    labeltype=i
	}

and noticed that the second button (labeltype=1) doesn't show anything
(a.k.a. it is FL_NO_LABEL), but the other types don't appear to work.
(labeltype>5 all also go blank.)
